I have an ItemType Item E that has an associated RelationshipType Item ED that references a third ItemType Item D. ItemType ED appears as a tab on ItemType E's form, and allows users to select an ItemType D.
We check that Item D is not related to TWO Item E's when user selects an item D under the Item ED tab. If it is greater than 2, we want to prevent the third from being entered. Our check is correct but the third is still listed under Item ED tab even when the client side method returns.
1) Is there a way to prevent the third from being added?
2) While trying to delete the third from Item ED, we need to reference Item E but cannot find a way to get its ID value. How can we get its ID value?
