Thanks so much for yoru response. I tried a few things from your response
and one solution solved the problem. I changed the ChoiceRenderer
constructor to include the "id" part. And it worked.
So here is the code:
form = new Form<IParameterMetaData>(
"form",
new
CompoundPropertyModel<IParameterMetaData>(parameterMetaData));
form.setOutputMarkupPlaceholderTag(true);
add(form);
form.add(choiceParameterInOutType =
new DropDownChoice<IParameterInOutType>(
"parameterInOutType",
listParameterInOutType,
new
ChoiceRenderer<IParameterInOutType>("name", "id")));
choiceParameterInOutType.setOutputMarkupPlaceholderTag(true);
Thanks again.
