Re: [rules-users] no visitor implementation for : class org.drools.rule.TypeDeclaration

Thank you for the explanation, Esteban. :) I'm sorry, but I have still some uncertainties about it. #1 I'm not sure if I've understood it correct. Is the message displayed every time a resource containing declares is modified or does is it displayed if the declare statements are changed? #2 The following extract of my original log extract says that the LHS of two rules has been changed. But I haven't modified anything on them. I've just deleted a rule. So what does it mean? Or am I missunderstanding the messages? Because for the the first rule no changes have been detected (and that is what I would expect for all rules except the deleted on.)

Modified resources are compiled, and a visitor pattern is used to loop over knowledge definitions (such as rules, functions, queries, etc.). So if rule1 was modified in the new resource, it is removed from the original kbase and replaced with the new implementation. The thing is that kagent doesn't implement a visitor for TypeDeclaration (when you use * declare* in your DRL to define your model) so it doesn't know how to handle them. I have recently fix a typo in the visitor implementation that prevented you to receive a better message: "BinaryResourceDiffProducerImpl: Couldn't handle "+yourDefinitionName+". We must leave it in the new Package." This means that kagent doesn't support modifications on declared types yet.
