Re: [flexcoders] Re: What comes after FlexEvent.INITIALIZE and FlexEvent.CREATION_COMPLETE?

Relooked at your code, wondering why are you doing this:

> > measuredMinHeight = measuredHeight = this.textField.height;

Is it really required? I think, its not neccessary and because of that your code is not working. You are right, textField might not have initialized.. But I think, measurement should still work, you don't need to explictly set measureHeights..

Try commenting that statement.,.

Thanks for the reply Abdul. However, if I remove the
FlexEvent.CREATION_COMPLETE listener, the checkboxes overlap each
other. Until I roll over them that is... once I roll over them they
each pop into the correct, non-overlapping position. I believe the
problem is that the textbox has not yet resized when INITIALIZE is
called. The behavior is virtually identical if I remove the INITIALIZE
listener, leaving only CREATION_COMPLETE; the items overlap until they
are rolled over. Very strange.

Any ideas?

Thanks,
Ben
