Subject: [Pythonmac-SIG] Argument is a block, but no signature available
Message-ID: <1E4A90C1-B222-4991-A0AF-1444718E059F@me.com>

I?m trying to use a Completion Handler block as an argument for a Cocoa AVMIDIPlayer method:

midiPlayer = AVMIDIPlayer.alloc().initWithContentsOfURL_soundBankURL_error_(midiFile, None, None)
midiPlayer.prepareToPlay()
midiPlayer.play_(myCompletionHandler)

But I get:

Argument 2 is a block, but no signature available

From what I can find out, this points to a bit in the metadata of PyObjC that needs a bit of work. Is that the case?

I?m using the default version 2.5.1 bundled with MacOS.

Thanks

Ben
