I try to run this in a unit test. The process variables are set when i start the process be calling

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.
