Hello.
I've still got problems with updating a page component from AJAX,
this time from a popup window.
Everything starts with a specific component for entering a date (it's
a special date, so I can't use the component provided with Wicket):
public class VRCDateField extends Panel
{
public VRCDateField (final String id, final IModelT<VRCDate>
date, final VRCDateModalWindow modal)
{
super(id);
final String notSet = "not set";
final Label label = new Label("label", new
DefaultModelT<String>()
{
@Override
public String getValue()
{
return DateFormat.format(date.getValue(), notSet);
}
});
label.setOutputMarkupId(true);
label.setOutputMarkupPlaceholderTag(true);
add(modal.createOpenLink("edit", date, label));
}
}
public class VRCDateModalWindow extends ModalWindow
{
private VRCDatePage datePage;
private Label label;
private IModelT<VRCDate> dateModel;
public VRCDateModalWindow (final String id, final Page page)
{
super(id);
setPageCreator(new ModalWindow.PageCreator()
{
public Page createPage()
{
datePage = new VRCDatePage(VRCDateModalWindow.this);
datePage.setDateModel(dateModel);
return datePage;
}
});
setInitialWidth(500);
setInitialHeight(170);
setResizable(false);
}
@Override
public void close (final AjaxRequestTarget target)
{
super.close(target);
target.addComponent(label);
}
public AjaxLink createOpenLink (final String id, final
IModelT<VRCDate> dateModel, final Label label)
{
final AjaxLink ajaxLink = new AjaxLink(id)
{
public void onClick (final AjaxRequestTarget target)
{
VRCDateModalWindow.this.dateModel = dateModel;
VRCDateModalWindow.this.label = label;
VRCDateModalWindow.super.show(target);
}
};
ajaxLink.add(label);
return ajaxLink;
}
}
I'm not attaching the whole listing of VRCDatePage, but the key
points are:
form.add(new AjaxSubmitButton("okButton", form)
{
protected void onSubmit (final AjaxRequestTarget
target, final Form form)
{
updateDate();
modalWindow.close(target);
}
});
where updateDate() updates the date model. Indeed the model gets
correctly updated since I see the new value gets to the database. But
the label doesn't get updated. I supposes everything was with the
setOutputMarkupId() and eventually with the
setOutputMarkupPlaceholderTag(), but clearly I'm missing something else.
