I have a very simple page which uses a form to update one page property
and a zone. Sourcecode and template see below.
It works as expected, the page property and the zone is updated as intended.
But whenever I use a the FormLayoutMixin on the form, "somePageProperty"
won't be updated anymore. The mixin doesn't do very much but render some
html before and some after the form, so I don't understand this odd
behaviour.
I tested this with 5.0.14 and 5.0.15-SNAPSHOT on Windows XP with Jetty 6
and FF3.
