That's probably best done with a pull model
IModel<List<Categoria>> allCategoriesModel = new
AbstracReadOnlyModel<List<Categoria>> {
@Override
public List<Categoria> getObject() {
return categoriaDao.getAllCategorias();
}
}
categoriaPai = new DropDownChoice("categoriaPai", categoriaPaiModel,
allCategoriesModel, choiceRenderer);
If the dropdown values should change when needed, you
shouldn't just fetch the data on component creation and
populate the dropdown with it, but have the model get
fresh data on every render.
Best wishes,
Timo
