Sorry I didn't catch this earlier, but I had the exact same problem. It
would seem that when you use Spring's @Transactional annnotation, the
class gets proxied... Which I would think is okay, except for the fact
that inherited methods (such as ActionSupport.input()) do not make it
into the proxied class. :(
For me, I simply re-factored the @Transactional method out into a
service class that I have injected into my Action class. IMO, it's ugly,
but it works.
