[rules-users] Guided Rule Editor doesn't list no-setter-fields if a fact is annotated

[Michael Anstis]

I'm not clear on what you are saying.

We reflect the methods of existing beans:-

   - If the member has a getter it is available in the LHS
   - If the member has a setter it is available in the RHS
   - If the member has a getter and a setter it is available in both the
   LHS and RHS

Members of declared types are available in both the LHS and RHS (as we
implicitly create getters and setters).

I don't understand "we should only support getters" but "be intelligent
enough not to allow the setter to be used in the IDE". If we only support
getters there is no setter; and if there is no setter how do we allow the
user to set the value? Of course my comments are from a Guvnor perspective,
if you mean to change the way declared types work, then... well, we'll have
to change Guvnor anyway :)
