# Today's lesson on introspection
Code introspection is great; the bean idiom is cool in many ways. The only caveat of course is that you can't catch f(oul)-ups at compile time and if you're not honouring the design contract, you learn the hard way. Having spent the better part of half an hour trying to figure out why an ActionForm bean wasn't picking up the a form submit value, and knowing that it had to be something stupid I was missing, I realised the getter/setters for these new button properties had default package scope, and so the damned Introspector that Struts uses couldn't see them. Aaaargh!
