I've answered my own question following "sleeping on it"...
The serialVersionUIDs hadn't been updated for a couple of files, meaning that
they wern't recognised as being new - presumably something got serialized at
some point....!
Am installing the ant task serialver to automate the process of updating them
for the future!

Subject: Support for Java 5 - Generics in Tapestry 4.0.2
Hi,
I've been having fun writing a page in Tapestry, but I could see a lot of
duplication about, so I introduced generics, with various objects that get
injected by hivemind also extending generic objects.... big mistake.
The problem is... I am now getting errors to the effect of "method doesnt exist
methodName(path.to.BaseGenericClass);"... This is a little concerning as I
don't really want to have lots of duplication everywhere unless I absolutely
have to.
Is this a known problem with Tapestry 4.0 that is fixed in 4.1?
Thanks
Gareth
