I'm trying to debug a problem where an NSOutlineView, as part of a drag, tries to create an instance of NSURL using "- (id)initWithString:(NSString *)URLString relativeToURL:(NSURL *)baseURL" with a nil string and get the following error:
*** Ignoring exception 'NSInvalidArgumentException' (reason '*** -[NSURL initWithString:relativeToURL:]: nil string parameter') raised by <NSOutlineView: 0x2d6a1a0> during a dragging session It happens *after* I write the dragging items to a NSFilesPromisePboardType pasteboard type. I have no idea where this NSURL is created. I have tried to create a subclass of NSURL and make that class to pose as NSURL but then, I'm getting all kind of unknown messages sent to instances of various classes like: -[NSCFString absoluteURL]: unrecognized selector sent to instance 0x30e940 or -[%NSURL length]: unrecognized selector sent to instance 0x503930 I also set a future break on [NSException raise] but it's doesn't break on that call. How can I find where this initWithString:relativeToURL: comes from? The problem is that it doesn't always happen. I tried to reproduce it but so far, I'm not sure what I'm doing different that will trigger the bug. The drag is from my app to the Finder. If I drag from within my app, the error never occurs. It really seems to be with the NSFilesPromisePboardType pasteboard type that this happens. Anybody have any suggestion? Thanks in advance! -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://nemesys.dyndns.org Logiciels Nemesys Software [email protected] Photo Gallery Store: http://laurentdaudelin.shutterbugstorefront.com/g/galleries _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
