I empirically found out what the solution was to the problem of not
selecting the correct default choice of the Manufacturer within Product!
I added a ChoiceRendered to the constructor of DDC and it did the trick!
Here's the form:
private final class EditProductForm extends Form {
public EditProductForm(String id, Product product) {
super(id, new CompoundPropertyModel(product));
Product p = (Product) getModelObject();
System.out.printf("category: %s", product.getCategory
().getName());
System.out.printf("manufacturer: %s", product.getManufacturer
().getName());
add(new RequiredTextField("name"));
add(new RequiredTextArea("description"));
add(new RequiredTextField("sellValue", BigDecimal.class));
add(new RequiredTextField("units", Long.class));
add(new CheckBox("onSell").setRequired(true));
add(new DropDownChoice("category", catalogService.getCategories
(),
new ChoiceRenderer("name", "id")));
add(new DropDownChoice("manufacturer", catalogService
.getManufacturers(), new ChoiceRenderer("name", "id")));
}
@Override
protected void onSubmit() {
Product product = (Product) getModelObject();
product.setEntryDate(new Timestamp(System.currentTimeMillis()));
adminService.updateProduct(product);
setResponsePage(ViewProductsPage.class);
}
}
Cheers for all the help!
Best,
James.
