Detect when a field changes

[Bruce Pokras]

For some reason (lost in antiquity) I have a script in which after "putting" text into a field via script I then send a "closefield" message to the field. Any idea if that would help in this situation?

I recently decided there should be an unlockMessages message that custom controls and cards are sent so they can check themselves for initialisation if they happen to be now on an open card and didn't know about it etc... Although if everybody did that perhaps it makes lock messages redundant.

The other thing that occurs to me is perhaps the use case where you definitely want the scripts to fire is different to the one you don't so perhaps it would simplify backwards compatibility if it were possible to declare the setProp/getProp as required somehow rather than changing lock messages itself.
