Hi, I'm getting a NPE exception when using drools-persistence-jpa with Drools Flow (I'm working with the trunk version 28274). It occurs in MarshallerReaderContext (line 78, see link below) and seems to be a result of JBRULES-2149. When loading a WorkItemInfo from the database a MarshallerReaderContext is created without the ruleBase set. For the moment I have added another catch block for the NPE and call super.resolveClass(desc). This seems to be working correctly and would have been the behaviour before JBRULES-2149. Should I go ahead and create a JIRA issue for this, or what is the prefered way to get the fixed in the trunk? http://fisheye.jboss.org/browse/JBossRules/trunk/drools-core/src/main/jav... http://fisheye.jboss.org/browse/JBossRules/trunk/drools-persistence-jpa/s... https://jira.jboss.org/jira/browse/JBRULES-2149 Regards, Noel Keating Senior Developer DeCare Systems Ireland +353 21 492-5188 nkeating(a)decaresystems.ie blog.decaresystems.ie This e-mail and any files transmitted with it are intended solely for the individual or entity to whom they are addressed.
