I have a Client Query. On it I have a button in the Operations with Records that will go to a Case Query for the Client; No problem so far.
I want that button though to only show up if there are actually Cases for the Client. I tried putting the following in the "Applicable when" property...
ClientMaster.child_CaseMaster IS DEFINED
But now the button doesn't show up at all regardless of whether or not there are Cases attached to a Client.
I know this has to be simple, but what am I missing here?
