NSWorkspace bug

[Enrico Sersale]

After the new NSWorkspace implementation of the [performFileOperation:...]
and [selectFile:inFileViewerRootedAtPath:] methods, I've changed all the
GWorkspace's code to not inherit from NSWorkspace anymore. Now GWorkspace
is subclass of NSObject.

Then, I've written a little test-app to call these NSWorkspace methods and
to see if the corrispondent methods of GWorkspace are called.

Well, this doesn't seem to work because i get:

NSInvalidArgumentExeption: GSListener does not recognise
selectFile:inFileViewerRootedAtPath

and, then:

NSInvalidArgumentExeption: _FastMallocBuffer does not recognise
decodeValueOfObjCType:at:

It seems that NSWorkspace can't call a method of the app delegate if this
is not declared in NSApplication.h.

As a test, If I change, in NSWorkspace's
[selectFile:inFileViewerRootedAtPath:],

return [app selectFile: fullPath inFileViewerRootedAtPath: rootFullpath];

with any other method of NSApplication, ex.

[app application: self openTempFile: @"apath"];
return YES;

and implement this in GWorkspace, all works perfectly...
