Why can I select aliases but not symbolic links in NSOpenPanel?

Question

I want to create an NSOpenPanel that can select any kind of file, so I do this

NSOpenPanel*    panel = [NSOpenPanel openPanel];

if([panel runModalForTypes:nil] == NSOKButton) {
    // process files here
}

which lets me select all files except symbolic links.
They're simply not selectable and the obvious setResolvesAliases
does nothing.

What gives?

Update 1: I did some more testing and found that this strangeness
is present in Leopard (10.5.5) but not in Tiger (10.4.8).

Update 2: The code above can select mac aliases (persistent path
data that lives in the resource fork) but not symlinks (files created with ln -s).

Answer 1

I cannot reproduce this. I just tried it and it works just fine. If symlink points to a directory, it shows the directory content when I select the symlink and if the symlink points to a file, I can select it as well.

Of course if the symlink points to a directory, you can only select it if choosing directories is allowed

NSOpenPanel * panel = [NSOpenPanel openPanel];
[panel setCanChooseDirectories:YES];
if ([panel runModalForTypes:nil] == NSOKButton) {
 NSLog(@"%@", [panel filenames]);
}

Answer 2

Your code sample worked for me, as well - I'm using 10.5.5 and XCode 3.1, if it matters.

If the alias is to a directory, I couldn't select the alias, since it resolved to the directory that it was pointing to, not the alias itself (the panel seems to resolve aliases by default). I was able to select an alias to a file, though.
