Forgive me if this one comes through a second time but I seem to be having a few difficulties getting my mails to go through. Hi Guys, I've decided to bite the bullet and try and move up to 4.01 but I'm having trouble getting the rules to compile. I have the following drl /******************* Code type rules ********************/ package au.com.codeprotechnology.online.ejb3.logic.common import au.com.codeprotechnology.online.bi.exception.ValidationError import au.com.codeprotechnology.online.ejb3.logic.constants.CodeTypeConstants import au.com.codeprotechnology.online.persistence.ejb.core.CodeType expander common.dsl rule "Code type is mandatory" when The code types type is null or empty then Send the message that the code types type is mandatory end rule "Long name is mandatory" when The code types long name is null or empty then Send the message that the code types long name is mandatory end rule "Short name is mandatory" when The code types short name is null or empty then Send the message that the code types short name is mandatory end rule "Short name too long" when The short name for the code type is too long then Send the message that the code types short name is too long end rule "Sort order is mandatory" when The code types sort order is null or zero then Send the message that the code types sort order is mandatory end With the corresponding dsl #Common domain specific language.

Used to work fine with 3 and I can't see any drastic differences between this and your examples in the documentation. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
