Need help eliminating superfluous 'Task Done' task

devodl

Given a simple Activiti workflow (e.g. Review-Approve) once the workflow has completed (i.e. been Approved or Rejected) I expect the workflow to end and any Listeners I defined for the "end" event to complete. Unfortunately this does not occur until the initiator of the workflow performs the mysterious "Task Done" task which I did not define in my workflow, is not required and adds no value. Many of our workflows are initiated automatically and the Initiators do not want to acknowledge each and every completed workflow "Task Done".

Help! How do I eliminate/skip/avoid the Task Done task?

Where is the Task Done task defined? It seems like it is independent of the BPM engine (jBPM or Activiti) and part of the Alfresco workflow framework that calls the actual workflow engine.

This old posting: https://forums.alfresco.com/en/viewtopic.php?f=34&t=24770 does not provide sufficient information for implementation and I suspect it refers to jBPM and not Activiti.

The solution to eliminate Task Done eludes me and any help would be greatly appreciated.

Steve

Hi,

Can you post your process definition file?

It's nothing special. I have been developing/testing using the out of box Review and Approve workflow: review.bpmn20.xml

Wait! Can I just remove the <humanPerformer> portion from the Approve and Reject tasks?

<humanPerformer>
                <resourceAssignmentExpression>
                    <formalExpression>${initiator.properties.userName}</formalExpression>
                </resourceAssignmentExpression>
            </humanPerformer>‍‍‍‍‍

How would I remove the <humanPerformer> using the eclipse plugin where it wants the Assignee set to some Performer Type?

Or do I change the Type of the Approve and Reject tasks from "User Task" to "Script Task" (or some other kind of task)?
If so does the "Script Task" need to do anything special to "complete" the task?

mitpatoliya

Hi steve,
You can remove the wf:approvedTask task.
then one more you need to change is in review task transition approve should lead directly to the end state rather then approved state.

Basing my learning on the out of box review.bpmn20.xml workflow I took the suggestion from @mitpatoliya to remove the User Tasks (Approved, Rejected) and route the decision directly to the End task. Here is the resulting definition:

In doing so I moved the simple Listeners (alfrescoScriptType) from the User Tasks to the <sequenceFlow>

if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;‍‍

Unfortunately now when the User approves the workflow it throws an error:
org.alfresco.scripts.ScriptException: 02302769 Failed to execute supplied script: 02302768 ReferenceError: "task" is not defined. (AlfrescoJS#1)
which implies that the JavaScript in the flow cannot reference the "task" object.

Summary
Original User Task for Approved between Decision and End

<userTask id="approved" name="Document Approved"
            activiti:formKey="wf:approvedTask" >
            <documentation>
                The document was reviewed and approved.

                        if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
                        if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;

                <resourceAssignmentExpression>
                    <formalExpression>${initiator.properties.userName}</formalExpression>
                </resourceAssignmentExpression>
            </humanPerformer>
        </userTask>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

New "Approve" Flow between Decision to End

<sequenceFlow id="flow7" name="Approve" sourceRef="reviewDecision" targetRef="end">
      <extensionElements>
        <activiti:executionListener event="take" class="org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener">
          <activiti:field name="script">
            <activiti:string>if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;</activiti:string>
          </activiti:field>
        </activiti:executionListener>
      </extensionElements>
      <conditionExpression xsi:type="tFormalExpression"><![CDATA[${wf_reviewOutcome == 'Approve'}]]></conditionExpression>
    </sequenceFlow>‍‍‍‍‍‍‍‍‍‍‍

So I'm puzzled why the original wf:approvedTask Listener could reference the "task" object but now the new <sequencedFlow> throws the error.

What you'd need to do is pass from the original UserTask to a Service task as follows:

<serviceTask id="approved" name="Document Approved"
         activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">
         <documentation>
            The document was reviewed and approved.
         </documentation>
         <extensionElements>
            <activiti:field name="runAs">
                  <activiti:string>System</activiti:string>
               </activiti:field>
            <activiti:field name="script">
               <activiti:string>
                  if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
                        if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;
               </activiti:string>
            </activiti:field>
         </extensionElements>
      </serviceTask>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

As you'll see the task does nothing but set the dueDate and priority. you could also directly get rid of the Approved and Rejected tasks and change the sequence flow 3 and 4's targetRef to end

Adei,
I'm getting more confused, my BPMN2.0 XML doesn't look anything like what you posted. I am using the Activiti eclipse plugin to model the workflow and when I create Service Tasks (to replace the User Tasks) the XML in the .activiti file looks like this:

Nowhere do I see any XML with the <serviceTask> element.
Are you using Activiti 5.9 and BPMN2.0?

Hi,

I'm not using the eclipse plugin to be honest just followed Alfresco's and Activiti's wiki sites to create it.

Checking your XML file doesn't seem you are creating service tasks but just removing them as you go directly from the review state to the end one and you are just adding listeners to each sequence flow (which is also fine).

In your previous post you said:

Basing my learning on the out of box review.bpmn20.xml workflow I took the suggestion from @mitpatoliya to remove the User Tasks (Approved, Rejected) and route the decision directly to the End task. Here is the resulting definition:

The xml looks the same as in that post.

Adei,
Thank you for your perserverance and sticking with me.
Starting with the out-of-box Review-Approve activiti process I have modified the process to create a workflow to skip the "Task Done" task three ways:
1 - Decision gateway goes directly to End (Mits sugggestion)
2 - Decision gateway goes to Script task (My idea)
3 - Decision gateway goes to Service task (Adei's suggestion)
Here is the workflow that uses a Service Task:

Regardless of which way (1,2, or 3) that I used to define the workflow when I attempt to Approve the Task I get the error:
"Failed to execute supplied script: 030211851 ReferenceError: "task" is not defined. (AlfrescoJS#2)"
which probably occurs when the Task tries to execute the Listener code:

if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;‍‍

It would appear that the "task" object referenced by the script is instantiated by the out-of-box workflow taskListener:

        <activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
          <activiti:field name="script">
            <activiti:string>if (typeof bpm_workflowDueDate != 'undefined') task.dueDate = bpm_workflowDueDate
if (typeof bpm_workflowPriority != 'undefined') task.priority = bpm_workflowPriority;</activiti:string>
          </activiti:field>
        </activiti:taskListener>‍‍‍‍‍‍

but not for the <serviceTask> or <scriptTask> tasks because those Task types do not declare or use the ScriptTaskListener.

It is clear I need to learn more about Activiti and how objects are passed to the different Task Listeners. I cannot simply change a task from <userTask> to <scriptTask> to <serviceTask> and expect the "task" object to still be available for reference.

Thanks again for your help.

I'm sure this has already been solved but my solution was to just put all the business logic into the first task itself depending on if it was approved or not. Here is my sample code
<blockcode>
<userTask id="decision" name="Decision" activiti:assignee="${initiator.properties.userName}" activiti:formKey="wf:activitiReviewTask">
      <extensionElements>
        <activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
          <activiti:field name="script">
            <activiti:string>execution.setVariable('wf_reviewOutcome', task.getVariable('wf_reviewOutcome'));
if(${wf_reviewOutcome}=='Approve') {
for (i = 0; i < bpm_package.children.length; i++) {
            var document = bpm_package.children;
            document.addAspect("wfa:reviewed");
            document.properties["wfa:reviewStatus"] = "approved";
            document.save();
}}else{
for (i = 0; i < bpm_package.children.length; i++) {
            var document = bpm_package.children;
            document.addAspect("wfa:reviewed");
            document.properties["wfa:reviewStatus"] = "rejected";
            document.save();
}}</activiti:string>
          </activiti:field>
        </activiti:taskListener>
      </extensionElements>
    </userTask>
