subview bindings not working in NSBox with bound hidden attribute

[dwc at dwci.net (David Christensen)]

Rick,

iCal and the like maintain their view manipulations with NSSplitView, 
which lets you do some fancy things as far as managing which views are 
displayed.  I have not played specifically with the bindings API and 
seen if NSSplitView responds as expected to the hidden binding, but you 
can use the standard NSView -addSubview: and -removeSubview: calls 
followed by an -adjustSubviews to your NSSplitView.

It would be interesting to see if the bindings implementation works 
with this as well.

HTH,

David
