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])
