Hey,
Thanks for supplying your code. I will take a look at it when I'm back at
office next week. As Thomas said, it would be cool if you open up a bug report
for Thant and add your code the. I will take care of that but then.
Thanks,
Martin

Hi there,
I've hacked a FormController to support unidirectional binding and added a
reset and a commit method. The code is available here:
<http://github.com/KnisterPeter/qooxdoo-formcontroller>
http://github.com/KnisterPeter/qooxdoo-formcontroller and could probably
integrated into qooxdoo core. :-)
Maybe I find some time and better integegrate this directly into the
FormController

Hi Martin,
yes we have the list controller already working. But we do not only want an
unidirectional binding. If we do that and have to specify all the
unidirectional bindings and model set operations on save manually, then the
databinding is of not much worth then.
It would be very helpful to have operations like the ones in the eclipse jface
databinding. There you have the possibility to sync from source to target and
from target to source with a method call. And during the binding setup you can
specify for each direction if it should happen automatically or on user behalf.
To make it more clear below is an example in pseudocode:
var model = { attr1: "value", attr2: "something" }
var f1 = new Textfield()
var f2 = new Textfield()
bind(model, "attr1", {sync: "automatic"}, f1, "value", {sync: "manual"})
bind(model, "attr2", {sync: "automatic"}, f2, "value", {sync: "manual"})
...
Then every value changes on the model will be shown immediatly in the view
fields, but changes from the view will not automatically propagated to the
model.
Finally on save button click you can call a method like this
"controller.syncToModel()" and everything from the view is pushed into the
model. No setter, no getter call required on the user side.
As far as I read the docs this is currently not possible with qooxdoo, isn't it?

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
