Hi,
okay, now I understood, why you don't want to use the JSON store. So now
back to your example.
Your problem with the second step was that your have overlook that the
request is asynchronous. The marshal should be done in the "complete" event.
Here your example, but the marshal is done in the "complete" event:
<code>
var label = new qx.ui.basic.Label("Default");
this.getRoot().add(label);
var req = new qx.io.remote.Request("http://localhost:6781/json/Test";,
"GET", "application/json");
var controller = new qx.data.controller.Object(null);
controller.addTarget(label, "value", "glossary.title");
req.addListener("completed", function(e){
var jsonObj = e.getContent();
var jsonModel = qx.data.marshal.Json.createModel(jsonObj, true);
controller.setModel(jsonModel);
});
req.send();
</code>
Cheers,
Chris
