I wrote the code in gmail, without the benefit of autocomplete or compile
errors. What I'm really getting at is that you should *always* add the
attribute modifier, which takes a model for the value to set the attribute
to. The model (either Model or AbstractReadOnlyModel, although the latter
is more appropriate for this) should then return the correct value based on
the logic
