Activiti custom workflow error on run + Alfresco 4

[msyepez]

Hello everyone. I've been fiddling with Activiti Designer for quite a bit, and even though I struggled deploying a custom workflow, everything seems to be fine now. Turns out I modified a workflow template (Parallel Review And Approve Activiti Process), so that when the workflow chooses the "reject" flow, an AlfrescoMailTask is run after the user reject task. That's the only change I made.

I deployed the bpmn20.xml file in \tomcat\webapps\alfresco\WEB-INF\classes\alfresco\workflow, and added the workflow definition on \tomcat\webapps\alfresco\WEB-INF\classes\alfresco\bootstrap-context.xml. The workflow appears now on the drop down list Share offers on starting a workflow; however, when I go through the reject path, this message appears when attempting to hit Next after the reject task:

org.activiti.engine.ActivitiException: Exception while invoking TaskListener: Exception while invoking TaskListener: 10140016 Failed to execute supplied script: missing } in compound statement (AlfrescoJS#6)

This is the bpmn20 xml:

Besides that, I'm not sure I understand how to use models… What's their purpose?  ops:

Well, silly me. I was missing a bracket on line 31. However, now I get the following error.

org.alfresco.scripts.ScriptException: 10140017 Failed to execute supplied script: missing ; before statement (AlfrescoJS#2)

And I can't detect a missing semicolon… This is the new bpmn20.xml:

Hi,

Did you resolve your issue?
I have similar problem with sending mail, it is happening because of this part of code in my process definition:

<userTask id="initiatorApprove" name="Alfresco User Task" activiti:assignee="${initiator.properties.userName}" activiti:formKey="wf:activitiReviewTask">    <extensionElements>     <activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">          <activiti:field name="script">            <activiti:string>            var mail = actions.create("mail");            mail.parameters.to = user@gmail.com;            mail.parameters.subject = "Subject";            mail.parameters.text = "Mail body";            mail.execute(bpm_package);            </activiti:string>          </activiti:field>        </activiti:taskListener>          </extensionElements>    </userTask>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Error message in log:
A system error happened during the operation: Exception while invoking TaskListener: Exception while invoking TaskListener: 10220099 Failed to execute supplied script: missing ; before statement (AlfrescoJS#1)
org.activiti.engine.ActivitiException: Exception while invoking TaskListener: Exception while invoking TaskListener: 10220099 Failed to execute supplied script: missing ; before statement (AlfrescoJS#1)

I guess that this script is incorrect but I can not see the problem in it.

Best regards,
Ivana

Hi again,

As soon as I have asked question, I tried to specify users mail in quotes ("") and it worked!
So, the working task in workflow xml looks like this:

<userTask id="initiatorApprove" name="Alfresco User Task" activiti:assignee="${initiator.properties.userName}" activiti:formKey="wf:activitiReviewTask">    <extensionElements>     <activiti:taskListener event="create" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">          <activiti:field name="script">            <activiti:string>            var mail = actions.create("mail");            mail.parameters.to = "user@gmail.com";            mail.parameters.subject = "Stigao je novi task na obradu u Alfresco";            mail.parameters.text = "Mail body";            mail.execute(bpm_package);            </activiti:string>          </activiti:field>        </activiti:taskListener>          </extensionElements>    </userTask>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope it will help someone.

Regards,
Ivana
