It gets there fine, its this line:
if (submit.getForm() == Form.this
that is the problem. submit (which is the button) does not belong to a
Form, it is supposed to contain a reference to a Form instead. SInce it
can't find a Form object for the button it throws an exception
throw new WicketRuntimeException("Could not find Form parent for " + this);
Thus killing the execution.
To Igor:
It didn't make a difference when I renamed (wicket:id) the button from
"submit" to "submitButton".
