How to get process variables in a taskListener?

c-shark

Hi!
I've got the following in my bpmn:

    <userTask id="assembleContract" name="Assemble Contract" activiti:candidateGroups="${candidateGroups}">
      <documentation>doc…</documentation>
      <extensionElements>
        <activiti:taskListener event="create" expression="${orgContractRegService.createOrganizationAndProfile(task)}"></activiti:taskListener>
      </extensionElements>
    </userTask>
‍‍‍‍‍‍‍‍

And the corresponding java code:

  public void createOrganizationAndProfile(DelegateTask task) throws Exception {
    LOGGER.info("Executing createOrganizationAndProfile() listener");
    task.getVariable("organization"); //null
  }
‍‍‍‍‍‍

The problem is that I can't get process variables in the listener. Interesting fact: the getVariableNames() is successful, I got back the variable names (but only the names…).
It doesn't work even when I give execution as parameter instead of task.
It works fine when I run it as a Service Task.

Can anyone help?
Thanks

where/how do you define the variables?

I try to run this in a unit test. The process variables are set when i start the process be calling
<code>runtimeService.startProcessInstanceByKey("my_workflow", processVariables);</code>
where <code>processVariables</code> is a <code>Map<String, Object></code>.
I don't think that something wrong with the process variables, because i'm not changed that part since I try to use task listeners instead of service tasks. And it worked with service tasks.

You can use the following lines to get the variable:

<blockcode>
DelegateExecution execution = delegateTask.getExecution();
String organization = (String) execution.getVariable("organization");
</blockcode>

Thanks.
I wrote that i tried with execution (as given by parameter).
I figured out that the problem wasn't in Activiti. I tried to print out a JPA Entity, that tried to fetch some other data, that is not existed at the moment. It was misleading that there was no exception which one might infer the real problem.
