Why 'Leave Alone' - Visible property of UI Policy Action overwrites setDisplay(True/False) on client script for a field?

[Pranshu3]

Hi all,

I have a client script onLoad to control display of a field based on GlideAJAX condition.
Also, there is a UI Policy Action controlling the 'Mandatory' feature of the same field, but Visible property is 'Leave Alone'.
Still, the setDisplay(True/False) doesn't have required affect.
So, does the UI Policy overwrite the client script even if selected 'Leave Alone'?
Then, how is 'Leave Alone' helpful at all??

Hi Pranshu,

Client script runs first then UI policy will run at the end;

Leave Alone means do nothing based on the conditions

Leave Alone: Does not change anything about the visibility of the field (useful if different UI Policies can affect different properties of the field)

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks

... and you can't hide the field if it is set to mandatory.

Thanks for the replies, due to mandatory fields, the hide action in client script was not working.
