+1 to moving the defaulting code to the renderer.
However, the renderer must call setFocusRowKey on the component with the
default value, so that
decode/validate/update will work correctly.
if the focusRowKey is null upon postback, it could cause errors during
decode.
Why? Shouldn't a null focusRowKey mean "decode everything"?
I'd prefer some reasonable behavior for this default, instead of
an absolute requirement on the renderer.
