Locking selection after trigger

[zagzebski]

I have a trigger that selects a value from a field when you activate a tab. What is the best way to then lock that specific filter so the user can't clear it?

How about 'Lock field' trigger after the 'Select in field' trigger. Did you try that?

Don't know how I overlooked that. Thanks!
