OnFinishedChangingProperties not called for Materials

Hello,

I am using the delegate OnFinishedChangingProperties from the DetailsView for my plugin. However, this delegate is not being called whenever a material is changed in the detailsview.
In SPropertyEditorAsset::SetValue the PropertyEditor is not valid, so it won’t set the value for the propertyhandle. I wonder if this is supposed to happen ? If so, is there another way to catch if a material is changed ?
