Hi All,
I'm running into a strange problem that I though perhaps someone else might
have run into and might have a solution for.
If I were writing a document based application in Objective-C and wanted to the
user to be able to cancel the opening of a document, I could do something like
this (which I can confirm works fine):
- (BOOL)readFromData:(NSData *)data ofType:(NSString *)typeName error:(NSError
**)outError
{
// Loading code here...
*outError = [NSError errorWithDomain:NSCocoaErrorDomain
code:NSUserCancelledError userInfo:nil];
return NO;
}
The (what seems to me) obvious thing to do in MonoMac would be to implement
this:
public override bool ReadFromData (NSData data, string typeName, out NSError
outError)
{
// Loading code here...
outError = NSError.FromDomain(NSError.CocoaErrorDomain,1376);
return false;
}
However, when I do so, my app crashes with the following stack trace:
#0 0x9287dfd5 in __wait4 ()
#1 0x93be04ec in waitpid$UNIX2003 ()
#2 0x0009fe9b in mono_handle_native_sigsegv (signal=11, ctx=0xbfffea5c) at
mini-exceptions.c:2192
#3 0x00004f6e in mono_sigsegv_signal_handler (_dummy=10, info=0xbfffea1c,
context=0xbfffea5c) at mini.c:5917
#4 <signal handler called>
#5 0x9249cd44 in objc_msgSend ()
#6 0x991622cc in -[NSDocumentController(NSInternal)
_fixedFailureReasonFromError:] ()
#7 0x9916b5f4 in -[NSDocumentController _willPresentOpeningError:forURL:] ()
#8 0x9916b197 in -[NSDocumentController
_openDocumentsWithContentsOfURLs:presentErrors:completionHandler:] ()
#9 0x9915f749 in -[NSDocumentController openDocument:] ()
(Rest of stack trace omitted)
Has anyone else run into this problem, and if so were you able to find a
solution/workaround?
Thanks,
Jon..._______________________________________________
