Hi,
I'm writing a small app which should enable the user to draw some
kind of flowcharts. I subclassed NSManagedobject for one of the
entities. Also wrote a subclass of NSView to do the drawing. I'm
using the NSPersistentDocument template from XCode as the basis for
my application. When I've an empty document and hit close then
everything goes fine. When I draw something on the view (and thus add
an instance of the custom entity to the model) the drawing is just
fine, but when I then hit close I get to question whether I want to
save the document. Choosing yes and picking a filename, the
application hangs. Sampling using Spin Control only shows me a list
of pointers, instead of method names. How do I find out where things
go wrong? Adding NSLog()'s to all my functions and see which one goes
wrong? I suppose it's somewhere in my entity, since the rest of the
app seems to work.
I've attached my custom entity perhaps somebody directly sees my
error. I only use the bounds methods at the moment to do the drawing.
Thanks in advance,
Remco Poelstra
