The problem is that the properties must be configured to fire an event when
the value changes; without this event, the Controller fails to bind to the
object to get even the initial value. Change your class to:
> qx.Class.define("my.kvp",
> {
> extend: qx.core.Object,
>
> properties:
> {
> key:
> {
> nullable: true,
> event: "changeKey"
> },
> value:
> {
> nullable: true,
> event: "changeValue"
> }
> }});
>
A tip is that when working in the playground, Qooxdoo¹s debug checks are
turned off so even in the debugger I couldn¹t pick up what was wrong as
soon as I copied & pasted your code into a skeleton application and compiled
with ³./generate.py source² I could see the problem straight away.

Subject: Re: [qooxdoo-devel] Fill Select Box via qx.data.controller.List
with Array of qx.Objects looks empty
Hello,
My tinyurl did not work, so here is my code:
qx.Class.define("my.kvp",
{
extend: qx.core.Object,
properties:
{
key:
{
nullable: true
},
value:
{
nullable: true
}
}});
var data = [];
var obj = new my.kvp();
obj.setValue("Hello");
obj.setKey("1");
var obj2 = new my.kvp();
obj2.setValue("World");
obj2.setKey("2");
data.push(obj);
data.push(obj2);
var kvparray = new qx.data.Array(data);
var selectBox = new qx.ui.form.SelectBox();
var controller = new qx.data.controller.List(kvparray, selectBox, "value");
this.getRoot().add(selectBox, { left : 50, top : 50});

Betreff: [qooxdoo-devel] Fill Select Box via qx.data.controller.List with
Array of qx.Objects looks empty
Hello,
I try to use the qx.data.controller.List to fill a Select Box with values
from an Array of my handmade Qooxdoo Objects.
But the resulting Select Box did not show the values as expected. It looks
³empty²
Please see my code on playground:

Thank you very much
