UI action on a reference field

[mlklein]

I'm a newbie learning scripting.   I want to add a UI action to a form.   This UI action adds a button when a field contains the word Test.   The word, Test, is selected from a list of services available to a certain user.

When I add the condition   current.u_category != 'Test' in the UI action condition then go to execute the form, the button appears on all the forms before u_category contains anything.

Do I need the clear the field first?   What am I not understanding?

Would this new button take the user away from the original form? What if you show the button and user clicks it   and changes the u_category?

I would still use the UI Action you've created, but wait to show the button until the record is saved, which is how the UI Actions work.
Good luck!
