Thanks, I'll do that. In the meantime I still need to get the job done asap. Can you provide me an example to implement such a logic using an inline-eval and global (which variable should be global?)? And just out of curiosity can you explain me why this code doesn't work (basically why, after the second line, $myList.contains($myObject) would return false): > $myList : List() from collect( MyObject(myField == "something") ) > $myObject : MyObject() from $myList > eval( $myList.indexOf($myObject) < 3 ) To me, this code seems to be just fine (in real Java it would be), so I can't understand why it doesn't work here. Maybe I am missing something or the DRL-Java code mapping done by a rule compiler is not so simple to figure out.
