NSTextField inside NSPopover is not key until mouse click

问题

I've got an NSPopover that is shown from interaction with an NSStatusItem. I've blogged about the hacks I needed to do to make input even possible in this situation here: http://blog.brokenrobotllc.com/using-nspopover-with-nsstatusitem

I have an NSTextField inside the NSPopover's content view. When I open the NSPopover, the NSTextField appears as if it is key (the cursor blinks). But, when typing, nothing shows up. If I click the mouse in the field, my input starts showing up there.

I've tried things like invoking NSWindow's makeFirstResponder upon popoverDidShow:. There was no change in behavior from this. Anyone have any ideas here?

My guess is you need to make your app active; try calling

[NSApp activateIgnoringOtherApps:YES];

when you show your popover.

Edit: Of course, I could be wrong. This is all just off the top of my head.
