Timeout when showing NSSavePanel

Question

When showing an NSSavePanel while the app is in background I get the following error:

RVS:__54-[NSRemoteSavePanel _runOrderingOperationWithContext:]_block_invoke_0319 : Timeout occured while waiting for the window
Remote Window Controller requested NSRequestRetryActivateSharedwindow...

Also, the panel doesn't appear and runModal returns NSFileHandlingPanelCancelButton.

The app is sandboxed. This is the code that creates the panel:

NSSavePanel *panel = [NSSavePanel savePanel];
NSInteger result = [panel runModal];
if (result == NSFileHandlingPanelOKButton)
{
    // Do something
}

What might be the problem?

If the app is in the foreground the panel is shown without any error.

damn ^^ this is hard... mhm not in a block... in main thread? I guess so... WHEN do you call this? — Daij-Djan, Dec 27 '12 at 20:18
Main thread. I already checked in the debugger, just in case. — hpique, Dec 27 '12 at 20:19
yip and WHEN? before appWilllFinishLaunching - from inside awakeFromNib? — Daij-Djan, Dec 27 '12 at 20:20
Gets called in a delegate method of the app delegate, after a long-running background operation finishes. The method is called in the main thread. — hpique, Dec 27 '12 at 20:26
and do you somehow block the main thread after the call somehow -- so that the window cannot be shown? some sleep ^^ or for(i<1000000000) or some calculation? — Daij-Djan, Dec 27 '12 at 20:28
Nope. I only call stopAnimation on a progress indicator before, but I removed that to test and it still fails. — hpique, Dec 27 '12 at 20:41
There's nothing after the `beginWithCompletionHandler:` call. — hpique, Dec 27 '12 at 23:28
Clarified that the app is sandboxed. Also simplified the example, as the problem can be also reproduced with `runModal`. — hpique, Dec 28 '12 at 02:18
are you running something else modal? or does the runloop not run by any chance? — Daij-Djan, Dec 28 '12 at 02:28
Nope. The only "odd" thing is that it only happens when the app is not in the foreground. — hpique, Dec 28 '12 at 03:04

Be sure to enable the appropriate entitlements. In this case, check that "User Selected File" is not set to "No Access".

It's set to Read/Write access. – hpique Dec 28 '12 at 22:58

For the "User selected file" entitlement of the Entitlement section from Summary tab of target setting should be set to "Read/Write" access.

The questioner already said that it is set to read/write. http://stackoverflow.com/questions/14060214/timeout-when-showing-nssavepanel#comment19462600_14076740 – Peter Hosey Mar 19 '13 at 16:49
