[Chameleon] problems modifying samples

For the record, there have been several discussions regarding how to
'disable' widgets. The correct way with version 2.0 is to either delete
it ;) or add enabled="false" to the attributes. Adding enabled="false"
allows you to keep it in your page, but the widget is completely skipped
by Chameleon.
Cheers,
Paul
