[rules-users] jaxb generated fact loaded into Guvnor throws errors when using the ' is contained in the comma separated list' operator

Hello , I am using 5.2.0.CR1 version of Guvnor . I have a jaxb generated class loaded through the model jar into Guvnor to be used as a fact in the Guided Decision Table editor. When I use a field ACTIVITYCODE of type String from the JAXB generated class with ' is contained in the comma separated list' operator, I get compilation errors. Unable to Analyse Expression ACTIVITYCODE == "A" || ACTIVITYCODE == "B": [Error: no such identifier: ACTIVITYCODE] [Near : {... ACTIVITYCODE == "A" || ACTIVI ....}] ^ [Line: 1, Column: 1] But when I use equal to operator to compare value to just a string value, it compiles fine. This rule fails. 3. | rule "Row 1 dds" 4. | ruleflow-group "None" 5. | dialect "mvel" 6. | when 7. | factClass : FACTCLASS( ACTIVITYCODE in ("A", "B") 8. | then 9. | factClass.setRATE( "5.25" ); 10. | end The below rule compiles fine. 3. | rule "Row 1 dds" 4. | ruleflow-group "None" 5. | dialect "mvel" 6. | when 7. | factClass : FACTCLASS ( ACTIVITYCODE =="A") 8. | then 9. | factClass.setRATE( "5.25" ); 10. | end Is this issue being caused by jaxb generated class? If so, is there a way to fix this problem? When I use a regular pojo that is not jaxb generated, the is contained in the comma separated list' operator works fine. Can someone provide any direction or thoughts on this? Thanks, Ram
