I am currently working with the ContentPaneFactory to generate ContentPanes and display them in a TabGroupPane.  The code below results in nothing rendered for this portion of the control.  I know the data is there, because if I remove the TabGroupPane (i.e. just have PaneFactory inside of the SplitPane), I see multiple panes tiled with the content in place.  Can anyone point me in the right direction with this problem?

Also, CustomPropertyContent is a list of objects that have two files, string Name and ContentControl Content.
