[rules-dev] Check matching between to sets of items

[Ringo CS]

Hi all,

I have a scenario as below:
   - object A has a list of items in B type
   - and a list of item in B type (*)
Now I want to check if list of items in object A has an item appears in list
mark as (*). If YES, stop the rule.
Could anyone show me how to archive that?

I appreciate it.

Ringo
