Can't do this in pageValidate but if you use Tacos, you can decorate a
getter method with @Cached which will cache the result for the lifetime of a
single request (
http://tacos.sourceforge.net/tacos4.1/tacos-annotations/index.html).

Hi

We have the same problem - which slows down our app to 
a level that is not acceptable. There probably is some pattern
that I have not picked up. Our hibernate beans are loaded
each time the ognl expressions read our objects. I guesss
there is some way to evict the hibernate loaded objects in the
prepare for render method, before the rendering happens in order
to avoid hitting the db for every property the ognl tries to read
from the object, or is there some better way?
