Hey,
that question is really interesting. So interesting I started up the playground
at home. ;)
So the fact is, that the form controller always sets up the binding in both
ways. But luckily, the form controller is not that much more than the object
controller in your case. The good thing is, with the object controller, you can
set up the binding uni-directional. I made up a little example to show you how
you can get it done but I omitted the list controller. Thats the part you
already have, right?

I hope that helps,

Hi there,
I have a question about the databinding.
We have the following UseCase in our application:
1) We display a list of json/model objects in a qx.ui.list.List widget
2) If the user selects one and pushes an edit button a new window is opened
3) In this window the selected model item from the list is displayed in a form
So far everything works well.
If the data is edited in the form, then this is propagated directly to the
model (as expected) but we would like the data to be transfered back on a user
specified event (a save button in our case).
How could we setup this using databinding? I could not find any documentation
on 'half-bidirectional' databinding.
Regards
Markus Wolf
