Start at DotSpatial.Plugins.AttributeDataExplorer.MainForm.RefreshData and BindData in the stack trace, then trace the active-layer change from LayerManager_ActiveLayerChanged. Reproduce the exception by changing the selected layer in the attribute data explorer and inspect the column and filter lifecycle around PopulateColumns. Done means changing layers no longer raises InvalidPropertyPathException for the missing Name1 property.
