    Hi Shen,

    this could be a matter of "timing". When calling the "loadData" method, you trigger an async request. This means, that when you try to get a property from the model there is no guarantee that the data is loaded already. You might consider registering an event handler on the "RequestCompleted" event of the model. Please refer to the API reference for more details.

    Regards, Frank
