Drools 3.1.0-M1 rules build 3.0.4 compatibility problems with eval statements ----------------------------------------------------------------------------- Key: JBRULES-718 URL: http://jira.jboss.com/jira/browse/JBRULES-718 Project: JBoss Rules Issue Type: Bug Security Level: Public(Everyone can see) Components: Drl Parser/Builder Affects Versions: 3.1-m1 Environment: windows 2k Reporter: Thomas Gonzalez Assigned To: Edson Tirelli Priority: Blocker Hi Tom - its great you are trying this out - once again - could you attach enough to reproduce this to a JIRA? It will get added to the integration tests. There is no fundamental reason why you can't cast like that at all, its certainly not a design constraint, just - SHOCK - a bug ! Say it isn't so !

Casting is required in some cases with out adding a good bit of extra work. Can you restore the support we previously had for casting with in an eval and retain the flexibility of using casts when needed? Thanks, Regards, Tom G
