How to pass strings to a subprocess

[bigp]

I tried to include a subprocess via CallActivity according to http://www.activiti.org/userguide/index.html#bpmnCallActivity
The chapter says that I can pass variables to the subprocess.
My problem is, that I don't have a variable in the main process, but I want only to pass a static string to the subprocess.
How can this be done without defining a variable (e.g. with a scripttask)?

Hi,

You may use the dataInputAssociation like this :


    <callActivity id="callSubProcess" name="Call activity" calledElement="SubProcess">
      <extensionElements>
        <activiti:in sourceExpression="Hello" target="myVar"></activiti:in>
      </extensionElements>
    </callActivity>

As you can see, the static string here is : Hello

And in the called activity you can print out the content in a ScriptTask like this :


    <scriptTask id="scripttask1" name="Script Task" scriptFormat="groovy">
      <script><![CDATA[System.out.println("myVar is : "+myVar);]]></script>
    </scriptTask>

This will print => myVar is : Hello

Hop this helps.

Hi,
okay so far.
The trick seems the difference between

<activiti:in sourceExpression="REVIEWER" target="taskAssignees"></activiti:in>

and

<activiti:in source="REVIEWER" target="taskAssignees"></activiti:in>.

The first line will transfer the value in the Variable taskAssignees, the second not.

How can I describe this difference in the Activiti Designer (Eclipse) without modifying the the …bpmn20.xml file every time?

Best,
phil

Hi,

It seems that the Designer doesn't implement this future. You may report a Jira issue for this (http://jira.codehaus.org/browse/ACT) ….
