Hi,
one of my users recently got an error when trying to save. My application is not document based, and I'm collecting the data to NSDictionaries, then save it with writeToFile: method. I never can reproduce the issue, so hard to find what is the problem.
I'm collection the data with methods like:
NSMutableDictionary *tempdict = [[[NSMutableDictionary alloc] init] autorelease];
[tempdict setObject:... forKey:...];
[tempdict setObject:... forKey:...];
[tempdict setObject:... forKey:...];
.
.
.
return [NSDictionary dictionaryWithDictionary:tempdict];
and putting those NSDictionaries to realSaveDict, then save:
[realSaveDict writeToFile:[sPanel filename] atomically:YES]
Any ideas guys what's going wrong?
Thanks,
Tamas
