Should Container Controls be receiving set calls on computed properties before the open event fires?
The computed property is NOT checked in the Inspector behaviour.
I guess converting to method pairs solves it
I don’t know why you couldn’t set computed properties in the constructor or another method before the Open event is fired. A container control is very similar to a window. I do stuff with Windows all the time before calling Show which triggers the opening event.
The container control is being used in a window and the framework sets the ide properties before calling open event. Which makes sense if they have been exposed in the inspector behavior. I am guessing the ide flagged it as needing the default value of empty string set.
