Bug: Infinite loop in [CPView isHiddenOrHasHiddenAncestors]
Reported by Lukas Berns | March 5th, 2009 @ 06:00 PM | in 0.7
If you have a visible CPView and call -(BOOL)isHiddenOrHasHiddenAncestors on it, you get an infinite loop:
- (BOOL)isHiddenOrHasHiddenAncestor
{
var view = self;
while (![view isHidden])
view = [view superview];
return view != nil;
}
if all superviews respond NO to -(BOOL)isHidden, view will become nil. because nil doesn't respond true to messages, you will get an infinite loop.
the while loop should be:
while (view && ![view isHidden])
