Version: 2.4

Process DemoTicketProcess

Overview

The DemoTicketProcess process is a sample BPMN process demonstrating automatic ticket routing (decision-making). Based on the evaluation result, the ticket is routed either through the Solution task or directly to the Verification task. Both branches always end with the Verification step before reaching the endpoint.

This document describes three process versions:

Version 0 - inline SpEL expressions directly in listeners (original approach)
Version 1 - delegate pattern with tsmScriptListenerExecutor and reusable scripts
Version 2 - task templates using the tsm:templateCode attribute (process created from predefined templates)

Process Diagram

The process diagram is shared by all versions - the process flow itself does not change:

Version 0 - Inline SpEL Expressions

Process Elements

1. Start Event (`Event_0nlkbod`)

The process entry point. No input condition is required - the process starts immediately.

2. Service Task: `Decision` (`Activity_12esote`)

Property	Value
Type	Service Task
Expression	`#{true}` (always succeeds)
Color	WHITE

Execution Listeners

This task has three listeners - two at start and one at end. All use inline SpEL expressions - logic is embedded directly in the expression attribute.

Listener 1 (start) - Ticket routing:

#ticket.priority == 'Blocker'
?
#ticket.chars.decision = 'solution'
:
#ticket.chars.decision = 'verification'

Checks ticket priority directly (no external script call)
If priority is Blocker, sets characteristic decision to 'solution'
Otherwise, sets characteristic decision to 'verification'

Listener 2 (start) - Decision description:

#ticket.chars.decision == 'solution' ?
#ticket.chars.decisionDescription = 'Resolve within 12 hours.'
:
#ticket.chars.decisionDescription = 'Resolve within 24 hours.'

Sets ticket characteristic decisionDescription based on the routing decision
If solution, deadline text is "Resolve within 12 hours."
If verification, deadline text is "Resolve within 24 hours."

Listener 3 (end) - Comment creation:

@comment.comment.create({
    ownerType: "Ticket",
    ownerId: #ticket.id,
    comment: #ticket.chars?.decisionDescription
})

Creates a ticket comment with the decision description text from decisionDescription
The comment is created under the currently logged-in user
Runs at task end, so decisionDescription from listener 2 is already available

3. Exclusive Gateway - Branching (`Gateway_13syha3`)

Branch	Condition	Target
Default	none (default flow)	User Task `Solution`
Conditional	`#{#ticket.chars.decision == 'verification'}`	Merge Gateway `Gateway_1bb2ay5` (skips Solution)

4. User Task: `Solution` (`Activity_14932so`)

Property	Value
Type	User Task
Assignee	`a4cb8448-c81c-46d0-9255-06d5191a56a4`
Default open status	`NEW`
Allowed statuses	`NEW`, `DONE`

Task Listener (event: `create`) - Notification on create

@notification.notification.sendNotification(
    {
        "templateCode" : "DemoTicketProcessCreation",
        "ownerId" : #ticket.id,
        "ownerType" : "Ticket",
        "data" : {"ticketId" : #ticket.id},
        "notificationTo" : {{"ownerId" : #ticket.creationUser,
                            "ownerType" : "User"}}
    }
)

Inline call to @notification.notification.sendNotification directly in the expression attribute
Sends a notification to the ticket creator using template DemoTicketProcessCreation

Task Listener (event: `complete`) - Notification on complete

@notification.notification.sendNotification(
    {
        "templateCode" : "DemoTicketProcessCreation",
        "ownerId" : #ticket.id,
        "ownerType" : "Ticket",
        "data" : {"ticketId" : #ticket.id},
        "notificationTo" : {{"ownerId" : #ticket.creationUser,
                            "ownerType" : "User"}}
    }
)

Inline call to @notification.notification.sendNotification directly in the expression attribute
Sends a notification to the ticket creator using template DemoTicketProcessCompletion

5. Merge Gateway (`Gateway_1bb2ay5`)

Merges both branches (from Solution and from the conditional skip) into a single flow leading to Verification.

6. User Task: `Verification` (`Activity_1183phb`)

Property	Value
Type	User Task
Assignee	`a4cb8448-c81c-46d0-9255-06d5191a56a4`
Default open status	`NEW`
Allowed statuses	`NEW`, `DONE`

Same base configuration as task Solution (assignee, statuses). No listeners.

7. End Event (`Event_19chu7e`)

Process ends after Verification is completed.

Services Used (Version 0)

Service	Usage
`@comment.comment.create`	Creates a ticket comment with decision description text
`@notification.notification.sendNotification`	Sends notifications to ticket creator (on `create` and `complete` in task `Solution`)

Version 1 - Delegate Pattern with `tsmScriptListenerExecutor`

Version 1 keeps the same process flow but replaces inline SpEL expressions with delegate tsmScriptListenerExecutor, which executes reusable scripts with parameters.

Changes Compared to Version 0

Service Task: `Decision` - Listener migration

The task keeps 3 listeners, but listeners 2 and 3 are replaced by delegate expressions:

Listener 1 (start, expression) - Ticket routing:

#ticket.priority == 'Blocker'
?
#ticket.chars.decision = 'solution'
:
#ticket.chars.decision = 'verification'

No change vs v0 - remains as inline expression.

Listener 2 (start, delegateExpression) - Script DemoTicketProcess:

<camunda:executionListener delegateExpression="#{tsmScriptListenerExecutor}" event="start">
  <camunda:field name="scriptCode" stringValue="DemoTicketProcess" />
  <camunda:field name="paramsJson">
    <camunda:string>{"decision":"#{#ticket.chars.decision}"}</camunda:string>
  </camunda:field>
</camunda:executionListener>

	Version 0 (inline)	Version 1 (delegate)
Type	`expression="#{#ticket.chars.decision == ...}"`	`delegateExpression="#{tsmScriptListenerExecutor}"`
Logic	Inline ternary setting `decisionDescription`	Script `DemoTicketProcess` with parameter `decision`

Uses delegate tsmScriptListenerExecutor instead of an inline expression
Executes script DemoTicketProcess, which sets decisionDescription based on the selected branch
Parameter decision is passed as SpEL expression #{#ticket.chars.decision}

Listener 3 (end, delegateExpression) - Script DemoTicketComment:

<camunda:executionListener delegateExpression="#{tsmScriptListenerExecutor}" event="end">
  <camunda:field name="scriptCode" stringValue="DemoTicketComment" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticketId":"#{#ticket.id}","comment":"#{#ticket.chars.decisionDescription}"}</camunda:string>
  </camunda:field>
</camunda:executionListener>

	Version 0 (inline)	Version 1 (delegate)
Type	`expression="#{@comment.comment.create(...)}"`	`delegateExpression="#{tsmScriptListenerExecutor}"`
Logic	Direct `@comment.comment.create` call	Script `DemoTicketComment` with parameters `ticketId`, `comment`

Replaces the original inline @comment.comment.create(...) from version 0
Runs at task end (end) so decisionDescription from listener 2 is already available
Creates a comment with the decision description text

User Task: `Solution` - Listener migration

In version 0, this task had inline listeners calling @notification.notification.sendNotification(...) directly. In version 1, they are replaced by delegate listeners with script DemoTicketNotification:

Task Listener 1 (create) - Notification on create:

	Version 0 (inline)	Version 1 (delegate)
Type	`camunda:taskListener expression="..."`	`camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}"`
Call	`@notification.notification.sendNotification(...)`	script `DemoTicketNotification` with `paramsJson: {"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCreation"}`

<camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}" event="create">
  <camunda:field name="scriptCode" stringValue="DemoTicketNotification" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCreation"}</camunda:string>
  </camunda:field>
</camunda:taskListener>

Task Listener 2 (complete) - Notification on completion:

	Version 0 (inline)	Version 1 (delegate)
Type	`camunda:taskListener expression="..."`	`camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}"`
Call	`@notification.notification.sendNotification(ticket, 'DemoTicketProcessCompletion', ...)`	script `DemoTicketNotification` with `paramsJson: {"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCompletion"}`

<camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}" event="complete">
  <camunda:field name="scriptCode" stringValue="DemoTicketNotification" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCompletion"}</camunda:string>
  </camunda:field>
</camunda:taskListener>

User Task: `Verification` - No changes

Task Verification remains unchanged in version 1.

Version 2 - Task Templates with `tsm:templateCode`

Version 2 uses the same listeners and scripts as version 1, but each task is additionally linked to a Task Template using attributes tsm:templateCode and tsm:templateVersion. The template defines complete task configuration (attributes, listeners, statuses) as a reusable building block.

Changes Compared to Version 1

New task attributes: `tsm:templateCode` + `tsm:templateVersion`

Each task in version 2 additionally contains:

Task	`tsm:templateCode`	`tsm:templateVersion`
Service Task `Decision`	`DemoTicketProcessDecision`	`1.0.0`
User Task `Solution`	`DemoTicketProcessSolution`	`1.0.0`
User Task `Verification`	`DemoTicketProcessVerification`	`1.0.0`

These attributes bind a task to its Task Template (see section Task Templates). Templates define default configuration, so attributes, listeners, and statuses are applied automatically.

New task element IDs

Tasks are recreated from templates and receive new BPMN element IDs:

Task	Version 1 ID	Version 2 ID
Decision	`Activity_12esote`	`Activity_09n8fih`
Solution	`Activity_14932so`	`Activity_1u8j2f4`
Verification	`Activity_1183phb`	`Activity_04xum8v`

Remaining configuration - No changes

Listeners, scripts, and runtime logic remain identical to version 1. The only change is adding tsm:templateCode / tsm:templateVersion on each task.

Comparison: Inline SpEL vs Delegate Pattern vs Task Templates

Overall Overview

Aspect	Version 0 (inline)	Version 1 (delegate)	Version 2 (task templates)
Logic definition	Directly in `expression` attribute	Script binding via `scriptCode` + `paramsJson`	Same as v1, but managed via template
Reusability	Logic tied to one concrete task	Scripts can be reused in any process	Whole tasks reusable as templates (`tsm:templateCode`)
Parameterization	Hardcoded in SpEL expression	JSON with SpEL references (`#{#ticket.id}`)	Same as v1
XML readability	Long escaped expressions in attributes	Structured XML with `<camunda:field>`	Same as v1 + template metadata
Parameter configuration	None - all in code	Form `Script.*.Params`	Same as v1
Testability	Must test through full process	Scripts can be tested independently	Scripts + templates can be tested independently
Notifications	Direct `@notification.notification.sendNotification(...)`	Delegate -> script `DemoTicketNotification`	Same as v1
Comments	Direct `@comment.comment.create(...)`	Delegate -> script `DemoTicketComment`	Same as v1
Process creation	Manual configuration per task	Manual configuration + delegate scripts	Template selection -> automatic configuration
Task versioning	None	None	`tsm:templateVersion` on each task

Example: User Task notifications

Version 0 - Inline expression:

<camunda:taskListener
  expression="#{@notification.notification.sendNotification({'templateCode':'DemoTicketProcessCreation','ownerId':#ticket.id,'ownerType':'Ticket','data':{'ticketId':#ticket.id},'notificationTo':{'ownerId':#ticket.creationUser,'ownerType':'User'}})}"
  event="create" />
<camunda:taskListener
  expression="#{@notification.notification.sendNotification({'templateCode':'DemoTicketProcessCreation','ownerId':#ticket.id,'ownerType':'Ticket','data':{'ticketId':#ticket.id},'notificationTo':{'ownerId':#ticket.creationUser,'ownerType':'User'}})}"
  event="complete" />

Version 1 - Delegate with script:

<camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}" event="create">
  <camunda:field name="scriptCode" stringValue="DemoTicketNotification" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCreation"}</camunda:string>
  </camunda:field>
</camunda:taskListener>
<camunda:taskListener delegateExpression="#{tsmScriptListenerExecutor}" event="complete">
  <camunda:field name="scriptCode" stringValue="DemoTicketNotification" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticket":"#{#ticket}","templateCode":"DemoTicketProcessCompletion"}</camunda:string>
  </camunda:field>
</camunda:taskListener>

Key changes:

expression="#{@notification.notification.sendNotification(...)}" -> delegateExpression="#{tsmScriptListenerExecutor}" with script DemoTicketNotification (reusable, configurable through form)
Parameters (ticket, templateCode) are passed via JSON instead of inline arguments

Example: Comment creation on the Service Task

Version 0 - Inline:

@comment.comment.create({
    ownerType: "Ticket",
    ownerId: #ticket.id,
    comment: #ticket.chars?.decisionDescription
})

Version 1 - Delegate:

<camunda:executionListener delegateExpression="#{tsmScriptListenerExecutor}" event="end">
  <camunda:field name="scriptCode" stringValue="DemoTicketComment" />
  <camunda:field name="paramsJson">
    <camunda:string>{"ticketId":"#{#ticket.id}","comment":"#{#ticket.chars.decisionDescription}"}</camunda:string>
  </camunda:field>
</camunda:executionListener>

Version 1 delegates this logic to script DemoTicketComment, which is reusable and configured through form Script.DemoTicketComment.Params.

Notification Templates

The process uses two notification templates for informing the ticket creator about task lifecycle events:

`DemoTicketProcessCreation`

Property	Value
Notification type	Direct
Name	Demo ticket process creation
Subject	Demo ticket process creation
State	Active
Config type	Ticketing
Delivery type	Email
Priority	Low

Sent when the Solution user task is created (create event). Notifies the ticket creator that the solution task has been assigned.

`DemoTicketProcessCompletion`

Property	Value
Notification type	Direct
Name	Demo ticket process completion
Subject	Demo ticket process completion
State	Active
Config type	Ticketing
Delivery type	Email
Priority	Low

Sent when the Solution user task is completed (complete event). Notifies the ticket creator that the solution task has been finished.

Script: `DemoTicketComment`

Script for creating a comment on a ticket. Used in the process for automatic comment creation.

@comment.comment.create({
    ownerType: "Ticket",
    ownerId: #ticketId,
    comment: #comment
})

Parameters:

#ticketId - ID of the target ticket
#comment - comment text

Form: `Script.DemoTicketComment.Params`

Form for script DemoTicketComment parameters. Contains two inputs:

ticketId - ticket selector via LOV (tsm-ticket-lov), wrapped in expression editor
comment - text input for comment text, wrapped in expression editor

Both inputs use layout widget dtl-fluent-expression-editor, which allows entering values as SpEL expressions.

Task Templates

Task templates define task configuration as a JSON array. They allow reusing the same set of attributes, listeners, and statuses across different tasks and processes. In version 2, templates are referenced directly from BPMN XML using attributes tsm:templateCode and tsm:templateVersion.

Task Template: `DemoTicketProcessDecision` (Service Task)

[
