I have a listview which is displaying in each row some data within a form,
among other things a date (as a label which is initially shown)
and a Panel containing a (wiquery-)datepicker (which is initially hiding).
Each row also has an edit-link (AjaxLink) and a save-link (SubmitLink).
After clicking the edit-link I'm hiding the date-label and display my panel
with the datepicker.
My problem is now that after clicking the SubmitLink I'm getting a
null-value from my datePicker.
If I am setting the visibility of my panel from the very beginning to
"true" and omit adding my panel to the AjaxRequestTarget within my AjaxLink,
everything
works as expected: the datepicker is returning the selected value.
What am I doing wrong here? How can I display my panel via Ajax and getting
anyway my form-values submitted?
I tried already several hours to find a solution, searched the mailing list
and web but I don't find any solution. So thanks in advance for any
suggestion.

PS:
Here are the relevant pieces of code:
My Listview:
ListView tiltos = new ListView("myList", myList)
{
@Override
protected void populateItem(final ListItem listItem)
{
Form form = new Form("form");
listItem.add(form);
// the actual date is set later in the code
final Label dateToBuy = new Label("dayToBuy", "keine
Angabe");
dateToBuy.setOutputMarkupId(true);
dateToBuy.setOutputMarkupPlaceholderTag(true);
form.add(dateToBuy)
final EditDatePanel editDate = new
EditDatePanel("editDate");
// if i set this to true and ommit the line later,
everything works
editDate.setVisible(false);
editDate.setOutputMarkupId(true);
editDate.setOutputMarkupPlaceholderTag(true);
form.add(editDate);
final SubmitLink saveLink = new SubmitLink("saveLink")
{
@Override
public void onSubmit()
{
// the output here is always null if the
editDatePanel
// is added to the AjaxRequestTarget (see following
lines)
System.out.println("test = " + editDate.getTest());
}
}
final AjaxLink editLink = new AjaxLink("editLink")
{
@Override
public void onClick(AjaxRequestTarget target)
{
dateToBuy.setVisible(false);
editDate.setVisible(true);
target.addComponent(dateToBuy);
// this one causes my form not to submit any values
// if I ommit it everything works
target.addComponent(editDate,
editDate.getMarkupId());
}
};
form.add(editLink);
}
}
The markup to my listview:
<table>
<span wicket:id="myList">
<form wicket:id="form">
<tr>
<td class="userListM">
<span wicket:id="editDate" />
<span wicket:id="dayToBuy">01.06.2010</span>
</td>
</tr>
</form>
</span>
</table>
My panel (which is, at least I think so, irrelevant to my problem):
public final class EditDatePanel extends Panel
{
private Date test;
public EditDatePanel(String id)
{
super(id);
DatePicker<Date> datePicker = new
DatePicker<Date>("datePicker", new PropertyModel(this, "test")) {
public void onModelChanging()
{
System.out.println("geht los jetzt!!!!!");
}
};
datePicker.setNumberOfMonths(new
DatePickerNumberOfMonths(new Short((short) 1)));
datePicker.setShowButtonPanel(false);
datePicker.setShowOn(ShowOnEnum.FOCUS);
datePicker.setOutputMarkupId(true);
datePicker.setOutputMarkupPlaceholderTag(true);
datePicker.setVisible(true);
add(datePicker);
}
public Date getTest()
{
return test;
}
public void setTest(Date test)
{
this.test = test;
System.out.println("test x: " +test);
}
}
The markup to my panel:
<wicket:panel>
<input type="text" wicket:id="datePicker" class="input80px"/>
</wicket:panel>

Add the entire form to the AjaxRequestTarget. The form's action URL is
out-of-date and pulls up the old version of the page.
Thanks for the answer. But if I'm adding my form to the target the
visibility of the components does not change anymore. Anything else I'm
overseeing?
