java.lang.IllegalArgumentException: The field 'script' should be set on the TaskListener

[paulclinton]

Hello,

What I am trying to do is to move a document to a specific folder on approve or reject of a Activiti workflow. I just found a piece of code to do this. The problem is when running the workflow and on Approve of the workflow I'm getting this error- 

java.lang.IllegalArgumentException: The field 'script' should be set on the TaskListener

Please help me out on this. Below is the script that I'm trying to execute-

TestWorkflow.bpmn.xml

<userTask id="alfrescoUsertask1" name="Alfresco User Task" 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><![CDATA[execution.setVariable('wf_reviewOutcome', task.getVariable('wf_reviewOutcome'));
logger.log("Review Outcome got");]]></activiti:string>
</activiti:field>
</activiti:taskListener>
<activiti:taskListener event="complete" class="org.alfresco.repo.workflow.activiti.tasklistener.ScriptTaskListener">
<activiti:field name="script">
<activiti:string><![CDATA[logger.log("Starting Excute Move Script");
if (task.getVariable('wf_reviewOutcome') == 'Approve'){
var dest= companyhome.childByNamePath("Sites/swsdp/documentLibrary/Approved");
bpm_package.children[0].move(dest);
}
else if (task.getVariable('wf_reviewOutcome') == 'Reject') {
var dest= companyhome.childByNamePath("Sites/swsdp/documentLibrary/Rejected");
bpm_package.children[0].move(dest);
}
]]></activiti:string>
</activiti:field>
</activiti:taskListener>
</extensionElements>
</userTask>

Solved this problem. The error was due to a simple error in the script.

Hi!

This error shows beacuse is missing the field script in the .bmpn structure of the service task item, make sure of define the field script as follows 

<serviceTask id="alfrescoScripttask1" name="Archivar evidencia" activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">
      <extensionElements>
        <activiti:field name="script">
          <activiti:string><![CDATA[//logger.log("example");]]></activiti:string>
        </activiti:field>
      </extensionElements>
    </serviceTask>
