Note to Cayenne/Tapestry users ...

["Michael Gentry (Yes, I'm a Contractor)" <mi...@fanniemae.com>]

I've been converting an application which uses Tapestry 3/Cayenne to
Tapestry 4 (and Cayenne, of course).  In the process, I've been trying to
get rid of all of the deprecated components (ActionLink, Conditional,
Foreach, etc).

I replaced one of the Foreach components with the new For component and it
caused issues for me.  I had a persistent List of Cayenne objects and
Tapestry, with the new For component, would serialize/deserialize them
(apparently in the HTML), which creates a HOLLOW Cayenne object
disassociated from it's DataContext.  (It also produced some bizarre HTML in
the hidden INPUT section -- kept repeating a For_0 variable, but with
different values.)  This, of course, caused the code to fail.

After looking through the docs, we added the volatile="true" attribute and
it made For work more like the old Foreach and everything was fine again.

Just thought I'd share in case other Cayenne/Tapestry users are going
through a similar conversion.
