Hi,
I'm trying to use a DropDownChoice to display and store the selected
category in the database. The value selected in the drop down is correctly
set, but when I look to the model (Category) of this drop down, it returns
always null. Do I do something wrong? Below some code.
public AddRecipeForm(String id) {
super(id);
setModel(new Model<Recipe>(new Recipe()));
...
add(new CategoriesDropDown("categories",
recipe.getCategory()).setRequired(true));
}
...
public void onSubmit() {
RecipeService recipeService = RecipeService.getInstance();
Recipe recipe = form.getModelObject();
Category cat = recipe.getCategory(); // This returns always null
}
...
private class CategoriesDropDown extends DropDownChoice<Category> {
public CategoriesDropDown(String id, Category category) {
super(id, new Model<Category>(category),
RecipeService.getInstance().getAllPersistentRecipeCategories(), new
IChoiceRenderer<Category>() {
@Override
public String getIdValue(Category category, int index) {
return category.getName();
}
@Override
public Object getDisplayValue(Category category) {
return category.getName();
}
});
}
}
Kind regards,
Hbiloo
