Enriching Jar Model with event annotations causes RuntimeDroolsException in guvnor ---------------------------------------------------------------------------------- Key: JBRULES-3121 URL: https://issues.jboss.org/browse/JBRULES-3121 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-guvnor Affects Versions: 5.2.0.Final Environment: Windows XP JDK 1.6.0_26 Tomcat 6.0 Guvnor 5.2.0.Final Drools-core 5.2.0.Final + dependencies Reporter: Scott Embler Assignee: Mark Proctor Attempting to validate a declared model (or build a package using such a model) that annotates an existing class as an event causes this: ERROR 07-07 10:45:42,789 (LoggingHelper.java:error:69) Unable to build asset. org.drools.RuntimeDroolsException: Field/method

org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:662) A curious thing to note is that the class this exception describes is a misspelling of the uploaded class ('org.drools.test.even.MyEvent' instead of 'org.drools.test.event.MyEvent') Another thing worth noting is that if the timestamp field is removed from the declaration, everything will validate. But, when the package is used to create a knowledgebase, objects of the class that was declared to be an event do not activate any rules. However, if the event declaration is removed completely, the rules will fire (but of course the facts will no longer be treated as events). Could the misspelling be causing this behavior? -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira
