add Dropdown object to List

[vahid ghasemi <va...@gmail.com>]

Hello guys.
I have a dropdown and I want to use CompoundPropertyModel OR PropertyModel.
the attribute of my model is List and the wicket can't set the
drop-down model object to List.
what is your option to handle this?

Selection is an object. If you want to transform it to a singleton later it
is a separate process. Or you need to build a model that does that, but for
PoC purposes I suggest you keep it simple and do by the book without list
at receiver.

I'd recommend: Keep it simple, implement using dropdownchoice and simply
convert to a list in your selection model if you need a list for domain
model purposes (I cannot comprehend why you would use a list to represent a
single selection).

You could use a validator for this
formComponent.add(new IValidator() {...});

Can I limit the users' choice number in ListMultipleChoice?

You need to use ListMultipleChoice instead of DropDownChoice.

So it's not any option to handle this issue?
I have list but it's singleton list :(

Choices model should be final and the selection model should be one item
not a list

Re: add Dropdown object to List

[vahid ghasemi <va...@gmail.com>]

model class :
class User {
private List<SomeThing> someThing;
}

Page class :
private User user;
Dropdown dd = new Dropdown("DropDownSomeThing", new
PropertyModel(user,"someThing", ....);

and this is my problem.
how can I add the drop-down model to the user property which is list, with
PropertyModel

Hi!

Can you paste some code with your exact (generic) variables which doesn't
work, it might be easier to figure out from code example than verbal
description?
