I'm using a Master-Detail layout for a simple Contacts file. I have a Portal with a cartesian relationship, which is used for Groups (much like Apple's Contacts app etc.). So all Groups are present in the Portal, whether there are related records or not, which is what I want. However, I'm wondering if there is a calculation I can use (for Hide Object) which can be used to determine if there are related records or not? I use a script, to Find related records when viewing Groups ... so not sure how to do this in a way that will constantly show the result ... i.e. via calc and not via script.
