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

Hi, #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? The message will appear every time a resource containing a type definition is modified. #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.) This is strange. This message should only appear if the LHS of a rule has changed. I will take a look to see if this is a bug.
