no, it doesnt really help since we cant see the bean that is inside
mySymbol.
as far as the example below:
see the use of loadabledetachablemodel below.
also you are specifying the same model for selection and list of
choices, that makes no sense. if whatever bean inside mySymbol model
has a "categories" property, then see my correction below.

I hope this helps.

Hi,
Thanks for the help... It's starting to make more sense to me
although still not working. The issue is definitely with the
form model. because all my sandbox experiments show me that
it all goes to hell when i introduce the model in the form.
My form is a a bean wrapped in a CompoundPropertyModel.
Maybe you can clarify below your explanation in that context.

if you type it it looks like this
DDC<T>(String,IModel<T>,IModel<List<T>>,IChoiceRenderer<T>)
the first model is the one that holds the selection, the
second is the one that holds a list of available choices.
the constructor with a single model:
DDC<T>(String,IModel<List<T>>,IChoiceRenderer<T>)
is used when you use DDC in combination with a compound
property model on the form, in which case the ddc's id is
used as a property expression into form's model to determine
the selection. there is a great wiki page on models.
so try this
myForm.add(new DropDownChoice("select",new Model(),new
MyChoices(),myRenderer));
this will create a ddc with a null selection. its not
practical, because to get the selection you have to call
ddc.getmodelobject(), but it will at least get you going
before you decide on what model to use.

hi,
I am new to wicket so I am not sure how simple this
issue is.
I am creating DropDownChoice components. I want to
a) build the the
Options from a list of Objects (not primitives) and b)
want to render
the option id and value as an attribute of the object in
the list. this
definitly works in the following sample code:
public class WicketSandbox extends WebPage
{
public WicketSandbox()
{
addPageTitle("Development Sandbox");
final Form myForm = new Form("form");
add(myForm);
final ChoiceRenderer myRenderer = new
ChoiceRenderer("name", "id");
myForm.add(new DropDownChoice("select",new
MyChoices(),myRenderer));
}
}
But as soon as I add an IModel to the form it seems that the
DropDownChoice looks up the choices in the form's
IModel. I have tried
to use the other constructors for the DropDownChoice
which require an
(String id, IModel model, IModel choices,
IChoicerenderer renderer) but
I can't figure out what is the difference between the 2
IModel objects
that have to be provided. If I provide twice a ref to
the same object I
get a different error:
The expression 'id' is neither an index nor is it a
method for the list class java.util.ArrayList
this is an improvement because it is accessing the right
object and
retrieving the list of choices but not extracting the
the objects from
the list as it does when I use (String id, IModel choices,
IChoicerenderer renderer).
In all cases if I remove the ChoiceRenderer my web page
builds and
displays but I see object.toString() values in my
drop-downs.
Any tips or pointers would be greatly appreciated.
