Hi there, Kindly assist. I am playing around with Inference and Truth maintenance I have 2 questions. 1) When doing a logicalInsert() in the consequence of a rule - is this the same as doing a insertLogical()? The reason I ask is that when creating rule in Guvnor it doesnt recognize logicalInsert() but recognizes insertLogical()? 2) Is there a way for Guvnor to create the inferred fact (dynamically) or must I create the inferred fact seperately and place in a jar and upload the the POJO model jar to Guvnor before the inferred fact can be logically inserted? Any help would be much appreciated. Thanks Devan -- View this message in context: http://drools.46999.n3.nabble.com/logicalInsert-and-construction-of-an-in...
