I've been doing quite a bit of digging on this, and here's what I've come up
with so far. It may not be all right, but it's what I'm going with for now
First, the "I has no properties" is irrelevant. It doesn't seem to actually
indicate a problem. I still get it on pages where the autovalidation is
working just fine.
Basically there seems to be a real problem with facelets and the way
woodstock performs actions.
I'll bet that in your pages for buttons you are using action instead of
actionExpression because actionExpression doesn't seem to work, but action
does. That's what I was doing, and I didn't really think twice about it.
It seems that facelets in some way is preventing the woodstocks normal
communications.
At this point in my (rather large mission critical) project I'm in the
process of dumping facelets and going with straight jsp pages. If you do
this you'll probably also notice that the jsp validation is much more strict
and holds you to the taglib definitions. I had to do a fair amount of work
to get my pages to render again, not hard, just time consuming.
