Non-modal NSOpenPanel

[Rick Frankel]

Sherm-

I managed to send this message to the list buried in a reply to
a previous message (forgot to change the subject), so to avoid looking
like a complete noobie I'm sending it to you directly.

I am trying to open a non-modal NSOpenPanel. As a simple test, I
modified the CamelBones FileViewer:

    
$openPanel->beginForDirectory_file_types_modelessDelegate_didEndSelector_contextInfo(
        $self->{'_openPath'}, '', $fileTypes, $self,
        'openPanelDidEnd:returnCode:contextInfo:', undef
    );

When invoked, the panel flashes on screen and disappears. It does not
invoke the end selector.

Is this a bug in my understanding/implementation or camelbones? or
is something else broken? (FWIW, OSX 1.3.5)

tia,
