Probably lack of knowledge on how I would go about doing that ;-).
On a more 'meta' note: I like using hibernate and haven't done enough
research on hivemind to know how easy it is to integrate the two. So I need
Spring to act as my IoC and integration point with hibernate. I've tried
hard to maintain tier code that wasnt tightly integrated with other tiers.
The code in this page class doesn't require any context but hivemind. I'm
always open to more elegant solutions I just dont have enough
tapestry/hivemind knowledge yet to come up with it. If I could write a
wrapper to the InjectObjectWorker object and have that setup in a config
that may be a more elegant solution.
Thanks for the dialog,
Kevin
