[Rubycocoa-talk] Sporadic application failure

[Tim P. <he...@ti...>]

Hey all,

I've implemented PSMTabBarControl ( http://www.positivespinmedia.com/dev/PSMTabBarControl.html 
  ) in my application, however I seem to get random failures  
complaining like so:

`NSApplicationMain': NSGenericException - *** Collection <NSCFArray:  
0x5598d0> was mutated while being enumerated. (OSX::OCException)
	from /Users/timperrett/Desktop/RubyPSMTabDemo/build/Release/ 
RubyPSMTabDemo.app/Contents/Resources/rb_main.rb:22

Now, I only see this message (and subsequent crash) when I try to  
close a tab that is not currently selected. This however does not  
happen in the example that is coded in Obj-C (supplied in that  
download from PSM). Ive translated all the relevant code; the main  
difference being there example is document based and my translation is  
not. The framework obviously works (see the PSM example), but yet the  
translation does not.

Nib wise, I have tried with the PSM delegate both specified, and un- 
specified, but it makes no difference. This leads me to think that it  
must be trying to either do something back across the bridge thats  
illegal, or there might be some kind of conflict with RC?

Ive posted up a sample app here (and commented out any translated  
functionality that isnt essential): http://download.timperrett.com/software/RubyPSMTabDemo.zip

Anybody's thoughts would be much appreciated :)

Cheers

Tim
