Problems with CAConstraint

Hi,

I am trying to keep a sublayer quadratic and it's height (and width) should be the height of it's superview.

When I do the following:

[subLayer addConstraint:[CAConstraint constraintWithAttribute:kCAConstraintHeight relativeTo:@"superlayer" attribute:kCAConstraintHeight]];

The height is OK. But as soon as I try to adjust the width, the sublayer disappears completely:

[subLayer addConstraint:[CAConstraint constraintWithAttribute:kCAConstraintWidth relativeTo:@"superlayer" attribute:kCAConstraintHeight]];

Any ideas why?
