DropDownChoice losing selection after ajax update
Hi,
I have a simple DropDownChoice that holds male/female option. The
selected value is retrieved from the database fine. Now I have a modal
panel and when it closes it refreshes a certain portion of my screen
using ajax. However, when the ajax refresh comes back the selected value
gets lost. When I look in the ajax debug screen I see the list of
options coming back and the selected value is empty. This happens even
when I don't do anything with the value of the dropdown in the modal
panel, but simply refresh the dropdown. Any ideas? Here is some code:
The dropdown: (the list of options is an enum, mergedModel is a
LoadableDetatchableModel)
DropDownChoice sex = new DropDownChoice("sex",
new PropertyModel(mergedModel, "user.sex"),
Utility.arrayToList(new Sex[]{Sex.MALE, Sex.FEMALE}));
sex.setOutputMarkupId(true);
add(sex);
What happens when I close the modal panel: (the contentPanel gets passed
a reference to the modalPanel and the objects that need refreshing)
form.add(new AjaxSubmitLink("save") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form form) {
for (Component comp : updateList) {
target.addComponent(comp);
}
modalWindow.close(target);
}
});
The ajax response:
Thanks for any help!
Kind regards, Jonck

There can be many reasons... maybe you show more of the html and java
pages? Here is some previous discussion about such situations:

RE: DropDownChoice losing selection after ajax update
Martin thank you!! It was indeed the form in the ModalWindow causing the error.
I thought that nested forms was not an issue with Wicket but I guess it is?
Anyway, replacing the form on the ModalWindow with the one you suggested works
like a charm. Thanks again!
