Assigning a dynamic assignee to a user task getting error

Hi all

I am trying to assign a dynamic user to a user task using spring, similar to the example in the user guide.  If I take the example as the example here:

<userTask id="task" name="My Task" activiti:assignee="${ldapService.findManagerForEmployee(emp)}"/>‍‍

However, when I start the process instance, it goes directly to that usertask (via a service task) and can't locate the 'emp' property resulting the exception:

org.activiti.engine.impl.javax.el.PropertyNotFoundException: Cannot resolve identifier 'emp'‍‍

How can I set the 'emp' property before it gets to the user task?  Is there some way of creating a process instance but not start it so I can set the property?

Hi,

You can either pass the 'emp' value when starting the process, in the variable map
<br>runtimeProcess.startProcessInstanceByKey('processKey', variables)<br>
or set the variables in an execution-listener when the process starts:
<br><process id="executionListenersProcess"><br>&nbsp; <br>&nbsp;&nbsp;&nbsp; <extensionElements><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <activiti:executionListener class="org.activiti.examples.bpmn.executionlistener.ExampleExecutionListenerOne" event="start" /><br>&nbsp;&nbsp;&nbsp; </extensionElements><br>&nbsp;&nbsp;&nbsp; <br>&nbsp;&nbsp;&nbsp; <startEvent id="theStart" /><br>&nbsp;&nbsp;&nbsp; <sequenceFlow sourceRef="theStart" targetRef="firstTask" /><br>&nbsp;&nbsp;&nbsp; &hellip;.<br><br>public class ExampleExecutionListenerOne implements ExecutionListener {<br><br>&nbsp; public void notify(ExecutionListenerExecution execution) throws Exception {<br>&nbsp;&nbsp;&nbsp; execution.setVariable("variableSetInExecutionListener", "firstValue");<br>&nbsp;&nbsp;&nbsp; execution.setVariable("eventReceived", execution.getevent());<br>&nbsp; }<br>}<br>http://activiti.org/userguide/index.html#executionListeners
