AjaxEditableLabel ... but how to get the changed value?

[Dorothée Giernoth <Do...@kds-kg.de>]

I know this must be a stupid question for all the not-wicket-newbies, but I can't seem to find a solution.
I have a RepeatingView with AjaxEditableLabels that contain information from database:

	cell.add(new AjaxEditableLabel(cell.newChildId(), 
						 new Model(list.get(j))));

Now I want to write the changed information from these labels back into the database after the content has changed. Wouldn't be too much of a problem if I knew how to retrieve the changed value from the label. I really have no clue how to do that!

Hope someone can shed some light! Maybe just a tiny code fragment, that could help me. Thanx in advance!

Override the onSubmit() method, like this (untested, but you get the
gist):

cell.add(new AjaxEditableLabel(cell.newChildId(), new Model(...)) {
  protected void onSubmit(AjaxRequestTarget target) {
    super.onSubmit(target);
    String value = getDefaultModelObject();
    // persist value here...
  }
});

Alternatively, if you keep a reference to the model you pass to the
AjaxEditableLabel, you can read its contents at some other point.
