works as you'd expect. (The ChoiceRenderer() wasn't doing anything).
/Gwyn
getMyOptionValue() actually returns an Integer.
What I'm trying to acomplish is this:
in my Client object I have stored an Integer myOptionValue, and there
are 3 possible options, so I want to show an edit form with a
dropdownchoice with those 3 options and have the selected option to be
the one that corresponds to the Integer I have stored in myOptionValue.
For Integer(1) - Opt1, Integer(2) - Opt2, etc.

Re: [Wicket-user] DownDownChoice problem
How about...
add(new DropDownChoice(
options2,
new Model(getDefaultSelection(getMyOptionValue())),
OPTIONS) {
protected String getDefaultChoice( final Object selected ) {
return ; // remove Choose One prompt
}
});
};
private Integer getMyOptionValue() {
return new Integer(2);
}
private String getDefaultSelection(Integer i) {
return String.valueOf(OPTIONS.get(i.intValue()));
}

Re: [Wicket-user] DownDownChoice problem
This is wrong.This is mentioned before on the list: The model object that is the selected objectshould be the same kind of object that is in the choices (the list)that is just a one-one mapping.
so if your list is: final static List OPTIONS = Arrays.asList(new String[] {Opt1, Opt2, Opt3});thenc.getMyOptionValue()shoudl return one of those so Opt1, Opt2 or Opt3
if c can only return an int then the options list should just be a Integer array of those possible ints.And the getDisplayValue should return Opt1 for integer1 and Opt2 for integer2 and so on.Thats the idea.. The renderer gives you an method where you can return the display value of a real object.

so if your list is:
final static List OPTIONS = Arrays.asList(new String[] {Opt1, Opt2,

then
c.getMyOptionValue()
shoudl return one of those so Opt1, Opt2 or Opt3
if c can only return an int then the options list should just be a
Integer array of those possible ints.
And the getDisplayValue should return Opt1 for integer1 and Opt2 for
integer2 and so on.
Thats the idea.. The renderer gives you an method where you can return

Thanks! I solved it. I'll add the example to the wiki for future reference.

Re: [Wicket-user] DownDownChoice problem
what you do seems like it should work.so maybe what you can do is download wicket-quickstart project, add the minimum amount of your code to it to reproduce the problem and attach it to the email. that way whoever wants to help you can download the project and run it in the ide and see the problem live. makes it easier much easier for us to help you. -IgorOn 9/21/06, Dumitru Postoronca [EMAIL PROTECTED] wrote: Igor Vaynberg wrote: can we see a quickstart? -IgorI'm sorry but I don't understand what you mean.

Re: [Wicket-user] DownDownChoice problem
What does c.getMyOptionValue() return?
This...
public HomePage() {
add(new DropDownChoice(
options,
new Model(getMyOptionValue()),
OPTIONS)
{
protected String getDefaultChoice(final Object selected) {
return ; // remove Choose One prompt
}
});
}
private String getMyOptionValue() { return Opt2; }
}
works as you'd expect. (The ChoiceRenderer() wasn't doing anything).

No matter what client I select, it always shows me the first option.
