Thanks Mike, My rule definition is (the image cause is defined with the guided editor from Guvnor)
http://drools.46999.n3.nabble.com/file/n3141579/drools.jpg and the result source: rule "prueba" dialect "mvel" when Cuscar( UNB.size() == 0 ) then end Cuscar is defined in my model and it contains an ArrayList called UNB (with is getters and setters), Guvnor seems to recognize everything OK because it let me select the correct options for the type ArrayList from the drop down menu, but when i click the validate option it throws me this error: [prueba] Unable to wire compiled classes, probably related to compilation failures:[Error: no such identifier: UNB] [Near : {... UNB.size() ....}] ^ [Line: 1, Column: 1] the identifier that doesnt seems to recognize is "size()", I have already tryed this rule: rule "prueba" dialect "mvel" when Cuscar( UNB == null ) then end and it compiles just fine... I wonder if it has something to do with the strict mode that I posted in my first message?... Thanks so much for your help :) -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-5-2-0-Final-in-Tomcat-6-0-32-fail-to-compile-rules-tp3139077p3141579.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
