<blockquote type="cite">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.).
<div> 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 <b>declare</b> in your DRL
to define your model) so it doesn't
know how to handle them. </div>
<div>I have recently fix a typo in the
