Re: [Pyobjc-dev] Re: Multiple Nibs

[Bob I. <bo...@re...>]

I'm not sure.  That code is not correct.  You can't do this:
	myModal = MyModalPanel.alloc()
	myModal.init()

You must do this instead:
	myModal = MyModalPanel.alloc().init()

Or this:
	myModal = MyModalPanel.alloc()
	myModal = myModal.init()

This shouldn't be unfamiliar, this is how ObjC typically works too.

The showMyModalPanel looks suspicious otherwise, because if this is 
something coming from interface builder with outlets and such then you 
shouldn't be creating the objects yourself, they should be coming from 
the nib.

Otherwise you should produce a minimal example and one of us will take 
a look at it.  If this is a bug, then it may already be fixed as there 
have been a lot of changes recently, and there is a release right 
around the corner.
