Add field message when field is unlocked only

[erck]

I'd like to display a field message only when the field is unlocked. 
And have the message go away when the field is locked again. 

Is there a way to do this ? I was trying to use 

document.getElementById('incident.u_environment_unlock')

somehow , but the id for the field is different when its locked and when its unlocked. 

Any ideas ?

You can use a field's state change event to show or hide a message depending on whether the field is unlocked or locked. For example, you can add an event handler for a field that will display a message if the field is unlocked and hide it if the field is locked.
