javax.el.propertynotfoundexception: target unreachable, identifier [name] resolved to null

When I created pagination super class for seam action,
JBoss server threw this exception.

javax.el.propertynotfoundexception: target unreachable, identifier * resolved to null

The problem was JBoss deployment tools
that didn't deployed new super class's .class file.

I'm not sure, but I guess it ended up with class loader exception.

But bigger problem is!
Why no log evidence for this exception.
It is fatal and critical!

Thanks
