Hi Giovanni, Thanks for the quick response. I tried what you suggested the alternate suggestion and solves all problems :) Thanks so much. I removed the salience factor which I had added. It somehow made sure that the rule doesn't get fired only :P Just added a modify block to modify required data. Thanks so much. I am having one more problem with creating .brl files in eclipse. Could you help me on that?? When I create a Guided business rule in eclipse - the drop downs to choose the facts always turn out empty. I tried adding a .package with all my import statements, adding the .jar to the classpath everything. Nothing seems to work. Importing it from guvnor gives following error stack: com.thoughtworks.xstream.mapper.CannotResolveClassException: metadataList : metadataList at
