JBPM 4.3 EL cannot read null process variable - javax.el.PropertyNotFoundException is thrown -------------------------------------------------------------------------------------------- Key: JBPM-2777 URL: https://jira.jboss.org/jira/browse/JBPM-2777 Project: jBPM Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: jBPM 4.3 Environment: tested on windows vista and ubuntu 9.10 Reporter: Jakub Sobolewski Assignee: Huisheng Xu Fix For: jBPM 4.4 Attachments: jbpm-2777-2010-05-10.patch, JBPM-2777-condition-testcase.patch, jbpm-2777-patch, JBPM-2777.patch, test.zip, test_jbpmTestCase.zip, UelExpressionTest.java EL cannot read process variable set to null value. Variable is seen from Java code. When I try to access it in JPDL by EL expression javax.el.PropertyNotFoundException is thrown. Simple test case (maven eclipse project) in attachment - it contains 1 process definition and 2 tests which show the issue. Forum thread: http://community.jboss.org/thread/147447?start=0&tstart=0 reading variable cases: 1: var exists and has a non-null value - Java returns value, EL returns value 2: var exists and has value of 'null' - Java returns null, EL fails 3: var does not exists - Java returns null, EL fails In cases 1,2 EL and Java should behave the same way... I think that in case 3 too, but which behavior is right ?
