Hi there,

the way you can work with java script in a workflow is using a scriptTask, something like this:

 <scriptTask id="scripttask2" name="ScriptTask" scriptFormat="javascript">
      <extensionElements>
        <activiti:executionListener event="start" class="org.alfresco.repo.workflow.activiti.listener.ScriptExecutionListener">
          <activiti:field name="script">
            <activiti:string>
               //Javascript code here… 
          </activiti:field>
        </activiti:executionListener>
      </extensionElements>
      <script></script>
 </scriptTask>‍‍‍‍‍‍‍‍‍‍‍

But is strongly recommended to apply constraints in your workflow model for your forms, there you can apply aspects and constraints for your properties.

Here is a great explanation of the BPM Model for Alfresco's workflow http://docs.alfresco.com/4.0/index.jsp?topic=%2Fcom.alfresco.enterprise.doc%2Fconcepts%2Fwf-task-model.html

Good luck

Thanks for your answer - but thats not what I´m talking about.

Me: asking about field validation in a workflow form
You: writing about a scripttask in a workflow… ?!

Or did I misunderstand you?

Edit: At least you pushed me in the right direction. Thanks again!
