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.
Best,

Thank you for the explanation, Esteban. :)
I'm sorry, but I have still some uncertainties about it.

When working on incremental change-set processing mode,
Knowledge Agent performs a diff between the original and the
modified resources. 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.

Hi,
I'm getting a two red highlighted outputs in eclipse if
I modify my rules file during run time. Besides that the
modifications seem to work.
What does it mean?
The full output I get when the resource change is
detected is listed below. The bold lines are the
concerned ones.
Thanks for any help! :)
