I am not the authority, but I just solved this error myself.
You cannot pass objects directly to tapestry in hivemind. In brief,
have your DataContextService implement
org.apache.tapestry.engine.state.StateObjectFactory and return an
instance to itself. There is a page that I got some help on at
http://wiki.apache.org/jakarta-tapestry/Tapestry+Spring+SSO+ASO that
while not exactly what you need could help out.

I am new to hivemind and tapestry and I know that there are other ways
of doing this (and actually have got it to work those other ways) but
am trying to do things the way the tapestry and hivemind documentation
preach. I have been stuck on this for a little while now and it seems
to me that what I am trying to do should be working based on the
documentation I have read. However, I just reviewed a previous post on
this list from last December "Injecting registry services to POJOS"
and it looks like this person had the same problem as me. From that
post it looks like he eventually solved it using hiveutils. Before I
add another jar to my project and head in a different direction, I
would like to know what I am doing or where my thinking is wrong here.
