For idea object, I create a multi valued lookup for approvers such that the lookup gets the initiator_id field of the idea, find the company of the initiator from CMN_SEC_USERS and select the resources that are from the same company. In the query, I use the syntax C.ID = @WHERE:PARAM:USER_DEF:INTEGER:CREATOR@ where c refers to CMN_SEC_USERS table.
I create an attribute called Approvers a muti valued lookup and on attribute creation I map CREATOR with INITIATOR_ID.
When I put this attribute to create layout, it works.
No matter it is null or some values selected, when I put it on edit layout it doesn't work.
What might be the problem?
