Object reference not set to an instance of an object.

[tkardaridis]

Hi,

I am facing the following issue. When I am using the [GridColumn] attribute with Position and also the [NotMappedColumn] or the [GridHiddenColumn] I am getting error "Object reference not set to an instance of an object" on the creation of the GridClient.

var gridClient = new GridClient(q => GetGridRowsAsync(q, fetchMethod, gridName),
initialQuery ?? extraQuery, false, gridName, null, Statics.UICulture).AutoGenerateColumns() as GridClient;

When I remove the Position from the [GridColumn] attribute it works as expected, but unfortunately I have to reorganize the properties in the model with the order I would like to be in the Grid.

Any suggestions? Can you please check if that is a bug and fix it? Or if it is not, any suggestions on how to use both Position in GridColumn with the attributes NotMappedColumn and GridHiddenColumn?
