[rules-users] Fw: [drools-user] identity vs equality question - drools use of equals()

Hi, I have a similar problem when using objects from an external framework as facts : the equals method is invoked despite using the WM_BEHAVIOR_IDENTITYproperty. Here is an exmple reproducing this with JBoss Rules 3.0.5 : I have created a JBoss Rules project under Eclipse, and created 2 classes MyObject and MyObject2. These classes have hashCode() returning 0 and equals throwing a ClassCastException when comparing 2 object of different classes Actually, after debugging a bit, it seems that the equals method is invoked by the TruthMaintenanceSystem.assertMap, which has a hardcoded EqualityKeyComparator (never set to IdentityKeyComparator). The WorkingMemory.assertMap has its KetComparator set correctly to IdentityKeyComparator Also, the equals method is not called when the hashCode() method returns different values for different objects, which makes it a bit harder to reproduce the issue. This is a roadblock for using JBoss Rules in our context ; has someone any idea for a workaround?
