Update wicket Panel using dialog modal

Question

I have a panel that should be updated using data from a dialog Modul. In the Panels constructor, I have a datamodel which should populate components in the panel.

The Panel constructor looks like this:

      public MyPanel(String id, final MyDataMOdel aDataModel) {
    super(id);
            ....
          }

The panel is added in my page as:

       MyDataModel myDataModel = new MyDataModel();
    MyPanel myPanel = new MyPanel("myPanel", myDataModel);

In the Open Dialog setWindowClosedCallback method, I have my updated DataModel

            myModal.setWindowClosedCallback(new ModalWindow.WindowClosedCallback()
            {
                private static final long serialVersionUID = -1746088901018629567L;

                public void onClose(AjaxRequestTarget target)
                {
                    update myDataModel here
                    Got the updated datamodel here (I can see that it is updated)
                      target.add(myPanel)
                 ....

This way, I can't see the components in the panel got updated.

Answer 1

For the time being, I solved as follows:

    remove(myPanel);
    myPanel = new MyPanel("myPanel", myUpdatedDataModel);
    myPanel.setOutputMarkupId(true);
    add(myPanel);
    target.appendJavaScript("window.location.reload()");

Answer 2

Am not sure what your MyDataModel() is. But you can use shared wicket Models.

          Model<YourDataObjectToShare> dataObjectToSHare = new Model<YourDataObjectToShare>()
    {
        private static final long serialVersionUID = -6394439155356911110L;

        @Override
        public YourDataObjectToShare getObject()
        {
            return ... The Updated Shared data here
        }
    };

Then Pass dataObjectToSHare to the panels argument

Look this
