(Recent adopter of Qooxdoo, still struggling with how binding works)
I have two forms, one for entity A (say, Customer) and another for entity B
(say, Title).
The customer form is bound to the customer store. The title form is bound to
the title store. The customer form title widget (a list box) is has its own
list controller, which is also bound to the title store.
When I add a new title (or modify or delete an existing one) , I reload the
title store to as a cheap/heavy handed way to sync things up. Since the
customer form title widget is using the same store, the title select box's
list reflects any changes right away, which is what I wanted to achieve when
I decided both the title widget in the customer form and the title form
would be backed by the same store.
However, when the title store is reloaded, the existing selection in the
title select box in the customer form is disposed, and the first element
becomes selected, which is wrong. Unless the currently selected title was
deleted, it should remain selected (or the selection should have been
restored to the previously selected title). What is worse is that even
switching to a different customer and coming back to that customer, the 1st
title in the list is still the one selected, so it seems the title property
in the customer model also got modified.
I wonder if it is a matter of one binding winning against the other.
Anything I can do that will ensure that the existing customer title is
imposed to the select box selection instead of the other way around?
Here is the code that creates the title widget for the customer form:
var titleWidget = new qx.ui.form.SelectBox();
var titleStore = registry.stores['Title'];
var titleController = new qx.data.controller.List(null, titleWidget);
titleStore.bind("model", titleController, "model");
titleController.setDelegate({bindItem: function(controller, item, index) {
controller.bindProperty("values.name", "label", null, item, index);
controller.bindProperty("uri", "model", null, item, index);
}});
form.add(titleWidget,'Title', null, 'title');
Cheers,
Rafael
