if variable is bound to multiple columns, that should mean an implicit join on identity --------------------------------------------------------------------------------------- Key: JBRULES-232 URL: http://jira.jboss.com/jira/browse/JBRULES-232 Project: JBoss Rules Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Drl Parser/Builder Affects Versions: 3.0-rc2 Reporter: Michael Neale Assigned To: Mark Proctor Fix For: 3.1-m3 This is based on some discussions on the mailling list. So: m : Message(foo == "bar") m : Message(foo != "42") should be the same as m : Message(foo == "bar", foo != 42) this works as the same variable is "bound" each time. At the moment it rebinds. The "new" behaviour should be consistent with Jess, and it does indeed make things simpler from a users point of view, and DSLs much more powerful. Obviously if nothing it bound, then it is just as normal. It *may* be possible to do this entirely in the parser, not sure at this stage... further investigation required.
