<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,

<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 visitor

I'm getting a two red highlighted outputs in

work.<br>
What does it mean?<br>

The full output I get when the resource
