Jira issue filed: https://issues.apache.org/jira/browse/WICKET-922

Well, I'm just looking at the Form class. I can't say for sure if there
are any other problem areas or not, at this point I'm just mentioning
what's causing a compile error for me.

If we change Button to IFormSubmittingComponent, then in
onComponentTagBody, there is a problem with the following:

  defaultButton.isVisibleInHierarchy()
  defaultButton.isEnabled()

Since defaultButton is no longer a button, but isVisibleInHierarchy()
and isEnabled() are not defined in IFormSubmittingComponent, this won't
compile.

Also in appendDefaultButtonField, we have:
  defaultButton.getMarkupId()

Same problem.


If those get sorted out in the Form class, then maybe we can think about
looking at using the interface elsewhere.

>From a low-level perspective, just to get this to compile, I would say
we need to add those methods to IFormSubmittingComponent. But, from a
design point of view, I'm not so sure.


Cheers,
Dave
