Is there a replacement for the disabled attribute in af:table when migrating to tr:table?

Hi,
It seems that the disabled attribute is no longer available
in the
tr:table tag. Is there a substitute or workaround for this?
Previously
in the ADF table tag, the "disabled" attribute
could be used to indicate
an attribute in the bean used for the table row to indicate
that the row
was disabled. This would then cause the radio button or
checkbox for the
row to show as disabled.

There also seemed to be a bug with the disabled rows in that
clicking on
"Select All" or "Select None" when using
a multiple selection table
would still cause the row to be selected or deselected.
Has anyone else experienced this? Is there a fix/workaround
for this?

Thanks,

Richard
