Hello activiti people,i dont know if this was already answered, but i searched the forum and didnt find a thread on this.

Hey everybody,

i found a solution to this problem. Apparently, there was a change of JavaScript engine used in activiti (engine embedded in Alfresco) from Rhino to Nashorn and that may have caused the issue i described above. Jeff Potts commited a few days ago to modify the script task and make it a service task using <code>org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate</code> Java class.

Instead of the old variable declaration, wich doesn't work anymore:

<code>
<scriptTask id="scripttask1" name="Submit" scriptFormat="javascript" activiti:autoStoreVariables="true">
      <script>execution.setVariable('scwf_approveCount', 0); execution.setVariable('scwf_tpApproved', false);</script>
</scriptTask>
</code>

Here is the new way to write it using a service task:

<code>
<serviceTask id="scripttask1" name="Submit" activiti:class="org.alfresco.repo.workflow.activiti.script.AlfrescoScriptDelegate">
      <extensionElements>
        <activiti:field name="runAs">
          <activiti:string><![CDATA[admin]]></activiti:string>
        </activiti:field>
        <activiti:field name="script">
          <activiti:string><![CDATA[
              execution.setVariable('scwf_approveCount', 0);
              execution.setVariable('scwf_tpApproved', false);
          ]]></activiti:string>
        </activiti:field>
      </extensionElements>
    </serviceTask>
</code>

I have tested the changes, and now it works.
