Re: Trouble loading bundles at runtime

Hi Jon,

I tried that but that doesn't make a different, I also believe that 
the call [pluginBundle principalClass] loads the bundle according to 
the docs.
The problem seems in the cached plist which somehow is incomplete. But 
even if I load the plist using the filemanager like suggested 
previously on the list I can't get the nib to load, neither using 
loadNibNamed, nor even using NSNib initWithContentsOfURL. It seems the 
bundle is somehow crippled/cached and needs to be refreshed to bring 
it in the state it is when I would quit my app and relaunch it..
