Add your DDC to form and use SubmitLink instead Link.

form wicket:id=form
select wicket:id=docType /
[click me]
/form
FormVoid form = new FormVoid(form);
add(form);
form.add(getDocTypeDropDown(docType));
form.add(executeLink(execute));
private SubmitLink executeLink(String id)
{
return new SubmitLink(id)
{
@Override

System.out.println(docType.getDokar());
}

problem with Dropdown List
Hello,
I have a problem with dropdown list.
Even if I select values in the Dropdown list (see picture below), the member
variable docType is always null .
Unfortunately I have found no error. I hope you can see why this is.
Best regards, Mehmet

Re: problem with Dropdown List
Hi Mehmet, I think you need change this line:
@Override
protected void setTDokar(TDokar dokart)
{
dokar = *docType*; --
DocSearchPage.this.*docType
*=* *dokart;
}
anyway, why are you delegating the set/get model calls to
TDokarDocTypeDropDownChoice
? Won't be interest only use the parameter model to maintain the TDokar?

AW: problem with Dropdown List
sorry, in my Email is the folow method incorrect:
@Override
protected void setTDokar(TDokar dokart)
{
dokar = docType;
}
in source cod is in code looks like this:
@Override
protected void setTDokar(TDokar dokart)
{
docType = dokart;
}
docType is still null.

Re: problem with Dropdown List
If you are not submitting an form to send the selected TDokar from browser
to server, you can add an AjaxFormChoiceComponentUpdatingBehavior at
TDokarDocTypeDropDownChoice. Than when the user click the executeLink, the
selected TDokar will be at the DocSearchPage field.
