I investigated the matter further and it's quite obvious what's going on: NSKeyedUnarchiver, which is used to process the nib, uses -initWithCoder: self to initialize the objects from the nib. Now the -initWithCoder method for the NSWindowController class calls -versionForClassName on its coder and this method isn't implemented in NSKeyedUnarchiver and thus fails if a decoder of this type is used. NSCoder won't take the job because it declares that method a subclassResponsiblity, hence the exception. The change to use -versionForClassName in the -initWithCoder method of NSWindowController was introduced into gnustep with r26956. Few other classes from gui seem to have it. But I'm not sure whether to blame that change: Shouldn't NSKeyedUnarchiver actually implement -versionForClassName? I'm going to write a bug report for this latter. But it's good to know what's going on. > If you're working on this, then I can send you my initial work (which, > sadly, isn't much - I got distracted early on) if you like.

I would like having a look at your ETSocket code, but I'm not sure whether I'd make good use of it - I'm not yet very savvy with most of the low level stuff. What I did was write some stub code that does unicast service discovery via libudns and glue it into XMPPConnection. The motivation was that I thought that service discovery (and announcement) would be semantically coherent enough to outsource them into a proper ServiceKit someday. best regards Niels _______________________________________________ Etoile-discuss mailing list [email protected] https://mail.gna.org/listinfo/etoile-discuss
