Hello, I've created rule with guided editor in Guvnor, then tried to open this rule in drools-eclipse plugin - got exception. Drools version is 5.0.1. Also tried latest jbooss-tools set of plugins - problem is the same. Sample test case+ log from Eclipse are attached. http://drools-java-rules-engine.46999.n3.nabble.com/file/n982161/test2.zip test2.zip http://drools-java-rules-engine.46999.n3.nabble.com/file/n982161/log.log log.log Regards, Ivan -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/BRL-rules-created-in-...
