I don't believe this. If true, it would suggest that sandboxed Save panels are
so broken that no one could save anything without typing the correct extension.
In fact, I'm not seeing the behavior you describe. In an existing sandboxed app
of mine, there's an Export function that does the right thing. The code is like
this:

(The line labeled "<-- this" is, IIRC, the change I referred to earlier.
Originally, there was no need to supply the extension explicitly there, but
somewhere around 10.7, it became necessary.)
Because of "canSelectHiddenExtension", my Save dialog has a "Hide Extension"
checkbox. If it's unchecked, and I retype the file name text box without an
extension, the checkbox turns itself on automatically. If I type the correct
extension, the checkbox turns itself off automatically. (If I type an incorrect
extension, the checkbox turns on. I assume I'd get something like
"filename.def.abc" in that case.)
No matter whether the extension is shown in the text field, the Save panel
returns a URL with the correct extension. I have no idea why you might be
seeing different behavior. Except …

When comparing your code with mine, I realized that -[NSSavePanel
beginSheetForDirectory: …] was deprecated in 10.6. Try using one of the
non-deprecated methods. It *does* matter, with powerbox.
