I am getting the following error on one of my nodes and I am not sure why. The following code demonstrates what I am trying to do and the property I am trying to access is a uComponent multi tree picker.

    if (Model.MyProperty != null)
    {
        foreach (XElement item in Model.MyProperty.BaseElement.Elements("nodeId"))
        {
            myProps.Add(item.Value);
        }
    }

I am getting an exception whenever I try and access the property when no items have been selected. Is there a way I can test for this before trying to access the property? I would prefer not to stick it all in a try/catch although I guess that would work.
