Scoping same type of objects [message #1810127]

Hello,

I have the following rule:

('mcontroller' mcontroller1 = [DSLManagerController] access=DSLAccess 'mcontroller' mcontroller2 = [DSLManagerController] ';')

I defined 2 mcontroller objects: controller_1 and controller_2.

So a valid rule can be :

mcontroller controller_1 can-access  mcontroller controller_2

I want to scope the right part of my rule, where accessing the same controller will be an invalid entry or the autocompletition can not reach the controller of the left part of the rule.

For instance:

mcontroller controller_1 can-access  mcontroller controller_1

Should be invalid,

Regards,

Daniel.

Customize scoping.

Wrap delegateGetScope(ctx, ref) into a FilteringScope and Filter the description for the current object there

Pleas also consider to do this with a validation instead of scoping

Thank you for your reply.

Yes, by using a validation rule was pretty simple. Just for curiosity, How should I implement a solution with Scope? I tried some examples but couldn't get it. Do you have a code snippet for guiding me, with some explanations?

Regards,

Daniel.
