Hi - I've got a small issue with the Multi Node Tree Picker that I'd like some help with,

Umbraco v6.1.6 (Assembly version: 1.0.5021.24867)
Installed uComponents v6.0
Created Data Type and added property 'gridSelection' to homepage.
Setup everything, all looks good:



Gone to Content Area and chosen nodes that I've defined as selectable, which makes my list on the left.
Publishes fine. I can journey away from this admin page and when I return the selected nodes are still there.
So I assume these Node IDs are saved in this Property 'gridSelection' for Homepage.

Have tried numerous ways of iterating through these selected nodes, thinking I was using the wrong one. However, the first line checks whether this property is empty or not. It stops there because I think it thinks the property is empty. But returning to the Content Area I can see my selected list??

Have tried 'gridSelection' & 'GridSelection' in HasValue.

Im using the macro below:

@using umbraco.MacroEngines
@using umbraco;
@inherits umbraco.MacroEngines.DynamicNodeContext    
@{
    if (Model.HasValue("gridSelection"))
    {
        int[] nodeList = uQuery.GetXmlIds(Model.GridSelection.ToXml());      
        IEnumerable<DynamicNode> PublishedNodeList = Library.NodesById(nodeList.ToList());        
        PublishedNodeList = PublishedNodeList.Where(x => x.GetType() != typeof(DynamicNull) && x.Id > 0);                        
        dynamic multiNodeTreePicker = new DynamicNodeList(PublishedNodeList);

        if (multiNodeTreePicker.Any())
        {
            foreach (var item in multiNodeTreePicker.Where("Visible"))
            {                   
                <p>@item.Name</p>      
            }               
        }
    } 
}

Any help would be much appreciated. Thanks
