Disclaimer - I have not worked in Assets all that long....I am trying to do something extremely easy in theory.
I have a simple schema for lookups. One Object type - Departments - holds 50 departments and the bureau they fall under.
Another object type is Bureau, a list of 6 major Bureaus.
I added custom field for Bureaus in JSM and put it on the form limiting it to the schema and objecttype=Bureau. It works as expected.
I added another custom field for Department with Filter scope of objecttype=Departments and Filter issue scope of anyAttribute="(${customfield_10500})"
10500 is the custom field ID of Bureau.
This does not work. Admittedly the entire approach may be off but all I really want is two drop downs where the 2nd one only displays departments from the selected bureau. Clearly I'm missing something.
