I looked some more and found the following:
When it works, with my modification, FormComponent.getInputAsArray tries to
get parameters for the TextField named "more:moreForm:textfield". I looked
in the parameter map or the RequestFacade object and found these:
wicket:interface, wicket:ignoreIfNotActive, random, more:moreForm:textfield,
radioGroup and more:moreForm:submit. And it finds the TextField.
The version that fails is looking for TextField named "more:textfield". The
RequestFacade object has: wicket:interface, wicket:ignoreIfNotActive,
random, forma_hf_0, radioGroup and more:submit. Is there a problem with
"forma_hf_0?
