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/523243#523243 Author : Sebastian Schneider Profile : http://community.jboss.org/people/sebastian.s Message: -------------------------------------------------------------- I fully agree that the behaviour should be identical in the second case where the variable exists and is null. I am not sure about the third one but from a first sight I would say treating a variable which does not exist as a null value seems strange to me. Is there anything from about throwing an exception telling the variable does not exist in this case? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/523243#523243
