[rules-users] activationCancelled() not being executed?

[Fermion]

I don't think that I can add something of value to the discussion from this
point on as my expertise concerning Drools is quite limited. 

I followed Edson's advice and used ruleflow-groups instead of agenda
filters. This works like a charm and enables me to have my rules react as I
want.

might be a new users expectation of an agenda filter:


Drools Manual, 2.5.7.3. Agenda Filters wrote:

After I read this section of the manual, I was under the impression, that
the ONLY thing an agenda filter would do, was to prevent a rule from FIRING.
This would be the case if the "fire an "activation cancelled/skipped" for
the rules filtered out" fix would be implemented, as the rules filtered out
would then be treated as any other rule, apart from the fact that they do
not fire.

The other suggested solution might have it's own benefits, that I can't
judge at the moment. If the "not remove filtered out activations from the
agenda" fix should be implemented, I think that the manual should be updated
in order to inform people about the fact, that it is not only the FIRING
that is prevented by the agenda filter.
