Hi
I'm having a little trouble with a sheet. I have a document based application, that should show a sheet right after opening a document (the sheet is attached to the document window). I have subclassed NSWindowController (as the documents window controller) and ran the sheet from the windowDidLoad. Now my problem is, that the sheet is not displayed correctly. It is shown as if it were a normal window, except that it does not have a title bar. This is the log I get:
I "solved" the problem by waiting 0.01 seconds before opening the sheet. I used NSTimer to do this.
I'm running Mac OS X 10.6.5.
I got the same error when I ran a sheet from awakeFromNib in a clean project which I created only to find out if this bug is due to my project settings or something similar.
So my question: Am I doing something wrong? Are there any better workarounds than using a timer?
