User development, A new message was posted in the thread "JBPM 4.3 EL cannot read process property with null value": http://community.jboss.org/message/523219#523219 Author : Ronald van Kuijk Profile : http://community.jboss.org/people/kukeltje Message: -------------------------------------------------------------- In your test I see no test for this. In fact, the difference between a non-existent variable and one with the value of 'null' is none when retrieving from java. The executionService.getVariable(pi.getId(), "NoneExistentVariable") returns null as well, so null is seen by jBPM as 'none existent'. That is basically the bottom line. I'll try to find out more.So it is not that retrieving the value of a variable with null succeeds ;-)   Regarding your test, you can even reduce more. if you use the deployment method in JbpmTestCase, the teardown of the super class does the undeploy automagicallly. And there are also interesting additional assertions. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523219#523219
