UI Action

[vijaya469]

On incident table, if state changes to 'on hold' , a ui action should be visible on the form named "OnHold'. And when UI action is clicked a field named 'On hold reason' should be displayed on the form and after filling the reason, click on onHold button to save it. If incident state is something else, both ui action and ui field should be visible=false . how to do it?  Can anyone please help me

You just don't.

Put the 'on hold reason' on the form and hide it with a ui policy. It should only be visible (and mandatory) on 'state = on hold'. No buttons, just normal form functionality. You are describing a very complex solution that doesn't make sense.
