Wicket: form issue - modelObject does not get updated

[Tiya Khambadkone]

I have a page with 2 textfields (with validation as mandatory textfields). Both the text fields have their own save button for some reason.
Steps to reproduce my error :
1. Delete all the pre-populated data of textfield #1. Click Save #1.
[ Validation fails. Error message is received. As expected.]
2. Use Cancel button and reder to the previous page.
3. Use Edit button and again render to the original page with 2 textfields.
4. Delete the data from textfield #2.
5. Hit save #2.
6. Save is successful whereas expected is like before validation should fail.

I tried debugging. It seems that the modelobject contains the same old data before my textfield #2 data deletion.

Why ?

public class FEConfigPanel extends Panel {

public FEConfigPanel(String id, IModel model, FEConfigPage page) {
        super(id, model);
        this.page = page;
        setOutputMarkupId(true);

        add(new Label("chc", "FE Channel Configuration"));
        table = createTable(new FEConfigDataProvider());
        add(table);


        add(new Label("coc", "CC Properties"));
        createCoCForm();
        add(form);
    }

    private void createCoCForm() {
        form = new Form("form");
        form.add(new LabeledInputPanel("textfield2", "TF2", "TF2AsString", getConfigModel()));
        form.add(createSaveButton());
    }

Component createSaveButton() {
        SubmitLink link = new SubmitLink("save-link", form) {

            private static final long serialVersionUID = 304478671323141864L;

            @Override
            public void onSubmit() {
                   page.getModelObject();
                   ........
            }
        };
        return link;
    }

private DataView createTable(FEDataProvider provider) {
        DataView view = new DataView("table", provider, 10) {

            private static final long serialVersionUID = -5704194525968729363L;

            @Override
            protected void populateItem(Item item) {
                FEConfigEntry entry = (FEConfigEntry) item.getModelObject();
                item.add(new Label("textfield1", entry.getTetfield1()));
                ......
            }

        };

        view.setOutputMarkupId(true);
        return view;
    }

After trying to save textfield #2 : page.getModelObject still contains old value of textfield #2 and not the new

Whereas after trying to save textfield # 1 :
FEConfigEntry entry contains new model.

Why?
