Chart Binding Issue

[jseymour]

This could very well be an error on my part but I am getting an Null Reference error when attempting to data bind a ObservableCollection<T> to a Chart control in WPF.  I am attempting to drill down into an object contained in my collection as follows:

 

  <cfx:Chart         ItemsSource="{Binding Collection}"         Gallery="Line">           <cfx:Chart.AxisX>           <cfx:Axis>             <cfx:Axis.Labels>               <cfx:AxisLabelAttributes                 Format="Date"                 CustomFormat="M/d H:mm" />             </cfx:Axis.Labels>           </cfx:Axis>         </cfx:Chart.AxisX>         <cfx:Chart.Series>           <cfx:SeriesAttributes             BindingPath="TChildProperty.Property1"             BindingPathX="TChildProperty.CompletedOn" />           <cfx:SeriesAttributes             BindingPath="TChildProperty.Property2"             BindingPathX="TChildProperty.CompletedOn" />           <cfx:SeriesAttributes             BindingPath="TChildProperty.Property3"             BindingPathX="TChildProperty.CompletedOn" />         </cfx:Chart.Series>       </cfx:Chart>

 

Where "Collection" is my ObservableCollection<T> and "T" is my type in the ObservableCollection.  "TChildProperty" is a property from "T" and is an object itselft.  The properties off of "TChildProperty" are all valid and everything is populated.  Here is my stack trace:
