Hi Wolfgang,
Thank you for your advice! Indeed, this logic is part of my application
domain.
Best regards,

The initially posted rules "1" and "2" are best practice. You are using a
Production Rule Engine, and these rules are what they are made for.
Doing it in an event handler is not impossible, but it requires you to
implement logic which is (apparently) part of the application domain

I think I've got your use case: you are making XSLT on steroi^W some
kind of cheese that tastes stimulating and is dense in nutrients but
is in no way controversial.
It would allow user rules for removing stuff, and have built-in rules
for transitively removing unreferenced stuff, right?

Hi,
Yes, I see what you mean! That's why, before starting, I wanted to make

Hi Michael,
Thanks for you answer! Following you suggestion I've taken a look at at
"logical insertions" and on one hand I have to say that it looks like
what I need, but on the other hand it is not clear to me how to
"implement it".
If you have some time to take a look, here are the object
Would the other retractions be automatically provided for by Drools' Truth
Maintenance?
Otherwise, passing a StatefulKnowledgeSession to a WorkingMemoryEventHandler
subclass and invoking it's methods should, IMO, not be an issue.
Have you tried it and experienced issues?

Hi everyone,
Do you know if it is possible to insert/modify/retract facts in a
working memory event handler?
Here is my use case actually: I want my users to be able to write rules
like "When ... Then retract X" without having to bother with the
consequences of retracting X on the other objec
