I have this method that is run on the momento of the form construction
The List<Categoria> keyValuePairsTemp stores the values of the DropDown
private DropDownChoice criaCategoriaPaiDropdown() {
setOutputMarkupId(true);
choiceRenderer = new CategoriaChoiceRenderer();
getHibernateTransaction();
List<Categoria> keyValuePairsTemp = (List<Categoria>) CategoriaDAO
.getAllCategorias(hibernateSession);
Categoria categoria = null;
// Trata o caso de não existir categoria cadastrada
if (keyValuePairsTemp.size() < 1) {
categoria = new Categoria();
} else {
categoria = keyValuePairsTemp.get(0);
}
PropertyModel categoriaPaiModel = new PropertyModel(categoria,
"categoriaPai");
categoriaPai = new DropDownChoice("categoriaPai", categoriaPaiModel,
keyValuePairsTemp, choiceRenderer);
return categoriaPai;
}

"Two rules to succeed in life:
1 - don´t tell people everything you know."
--------
We shall go on to the end.
We shall fight in France
We shall fightover the seas and oceans.
We shall fight with growing confidence and growing strength in the air.
We shall defend our island whatever the cost may be
We shall fight on beaches, we shall fight on the landing grounds,
We shall fight in the fields and in the streets,
We shall fight on the hills.
We shall never surrender.
Winston Churchill
