[Rubycocoa-talk] Problem with YAML::load in AppController

[Stephyn B. <ste...@gm...>]

Hi all,

I have a very simple app I'm trying to write to spike out some key  
portions of an app I'm planning to write.

The application is not document based but I do want to be able to save  
and load the object model. The "preferred" form is YAML with import/ 
export using XML. The application is dirt simple. Just an array of  
Friends visible through a NSTable and the Friend objects themselves  
which can be edited.

I can successfully save the @friends array as a YAML file  
(saveFriends)...but I get thrown into the debugger every time I tried  
to load a YAML file (openFriends). I've narrowed it down to YAML::load  
as the line that crashes (I can read the file, and print out the  
contents to NSLog just fine).

Any ideas?

If you're curious and want to kick the tires, you can download the  
project at http://homepage.mac.com/stephyn/Friends.zip

Thanks a bunch.

Cheers,
Steve
