[SOLVED]Conditional actor assignment

[ljyanes]

Hi, I'm working on a workflow and trying to specify to who some task will be assigned. So far I was giving it this approach, the user on the task interface selects from a list containing the different departments on the organization, then on the transition from that task (the start-task) I would map their choice to the user responsible for that department. ATM I'm getting a

org.alfresco.service.cmr.workflow.WorkflowException: 09200004 actor expression must evaluate to a person

This is the processdefinition:

Hi,

<variable name="director" access="write"></variable>
‍‍‍

This does not mean that the result of the call of people.getPerson() will be put into the variable director.

Try the following pattern :

<action class="org.alfresco.repo.workflow.jbpm.AlfrescoJavaScript">
        <script>
            var contralor = people.getPerson('contralor');
            executionContext.setVariable("contralor", contralor);
        </script>
      </action>
‍‍‍‍‍‍‍‍

Ok, I'll try that and come back telling if it worked. Thank you.

[ljyanes]

Thanks that worked gracefully, hope this solution helps anyone else trying to make use of Alfresco Workflows

[jayjayecl]

No problem
I'm glad I could help you.

After having struggled on many areas of Workflow design, I now have a motto :
- prefer Java Actions to script actions
- use type and aspect properties rather than "variables" and "controllers"
- executionContext's methods setVariable and getVariable are your best friends
