I am trying to customize a work item template and need to add a field which can capture hierarchical data.I am using TFS power tools to edit work items. I tried to create a new field with datatype as TreePath but when I save it, it throws an error: TF26179 – Field Type 'TreePath' can be used only with System.AreaPath & System.IterationPath
Is there any workaround to use the TreePath control for custom fields?
