Problem with setting process variable on a usertask listener

Hi,I have a workflow whose first task has a listener attached to it. This listener performs some processing and then attempts to store the result in the activiti process variable. This doesn't work for me because I always get the exceptionSEVERE: Error while closing command contextorg.activiti.engin

Do you have the (minimalized) code of your listener?

Hi,

I have created a unit test in an eclipse project to demonstrate the issue and shared it via dropbox as I couldn't upload it to the forum. (https://www.dropbox.com/s/c144xoxd637oerl/Development.zip)

There is a method call verifyTestVariableValueCorrect which I am expecting to pass for both calls made to it. However, an exception is thrown in the listener which is attached to both tasks in the process.

I'd really appreciate any help that you can provide.

Thanks
Marc

Don't use the runtime service from inside listener, rather use the following:

delegateTask.getExecution().setVariable("", "");
