how to change the panel data from a modal window opened from AjaxLink.onClick() ?

2014-06-12 Thread Duke 
Hi all, dear wicket experts!
I have some issue in my code, I suspect that it is because of ajax behavior,
that I not quite understand.
I have a MyPanel extends CheckedFolderT, that I create in
NestedTree.newContentComponent() {}. This MyPanel has some public data,
boolean bChanged for example.  MyPanel has an AjaxLink that creates and
shows a ModalWindow using for edit a MyPanel data. 

MyPanel.java
public class MyPanel extends CheckedFolderT {
public MyPanel(String id, AbstractTree tree, IModelT model, ModalWindow
dialog, ...) {
...
AjaxLink link = new AjaxLink(editlink, model) {
  public void onClick(AjaxRequestTarget target) {
MyPanel.this.dialog.setWindowClosedCallback(new WindowClosedCallback() {
  public void onClose(AjaxRequestTarget target) {
if*(bChanged == true)* {
   //update Panel model, to show an updated in ModalWindow data in a
tree
   MyPanel.this.tree.updateNode(model.getObject(), target);
}
  }
}
MyPanel.this.dialog.setPageCreator(new ModalWindow.PageCreator() {
  return new EditPage(MyPanel panel, ...);
}
MyPanel.this.dialog.show(target);
  }
}
}
}

In an EditPage I try to modify MyPanel.bChanged field when a user changed
Panel data and try to close a Modal EditPage.
EditPage.java
...
protected void onSubmit(AjaxRequestTarget target, Form? form) {
   panel.bChanged = true;
   EditPage.this.modalWindow.close(target);
}

When ModalWindow closed, onClose(AjaxRequestTarget target) method in MyPanel
fired. But a bChanged is always false in it. Why?
And hence the more general question:
How can I know that data in a modal EditPage is changed by user?

Addition:

NestedTree and ModalWindow is placed on a TreePage:
TreePage.html
div wicket:id=modaleditdialog/div
div wicket:id=tree[tree]/div

TreePage.java

public TreePage () {
dialog = new ModalEditDialog(modaleditdialog);
dialog.setResizable(true);
dialog.setAutoSize(true);
dialog.setOutputMarkupId(true);
...
add(dialog);

NestedTreeT nestedTree = new NestedTreeT(id, provider) {
  protected Component newContentComponent(String id, IModelT model) {
MyPanel panel = new MyPanel(id, this, model, dialog,...);
panel.setOutputMarkupId(true);
return panel;
  }
}
nestedTree.setOutputMarkupId(true);
add(nestedTree);
...
}

Hi,

The problem is that EditPage when deserialized creates a new copy of
MyPanel instance and its bChanged member field.
The best/simplest way is to use a Panel as ModalWindow content instead of a
Page.
Another way to share bChanged between the pages is to store it in the
session (i.e. MySession#bChanged).
Yet another way is to get a reference to bChanged thru the first page:
- pass a PageReference of page1 to editpage and later use it:
pageRef.getPage().setChanged(true)

Thanks Martin! 

I tried to use a reference to bChanged through the first page, but it
permanently bind ModalWindow with first page and I cant use it in another
pages.

For the first way - There will be no serialization/deserialization when I
will use Panel insted of a Page in ModalWindow?

Best regards,
