I frequently create collections of things [mostly lists] and stick them into a VelocityContext for rendering into a web page. Lately, I've been getting a number of these exceptions, even when the class declaration in the hbm.xml file is lazy=true

Any ideas?

I should have said, "when lazy=false"

TIA
