DesignTimeVisible and TypeConverters

Does anyone know if it is possible to have both a DesignTimeVisible(false)
and a TypeConverter attribute together.

[ToolboxItem(false)
,TypeConverter( typeof( MyTypeConverter ))
,DesignTimeVisible(false)]
public class ExplorerGroup : Component
{...}

I use this object in a collection and don't want the objects to be
manipulated except by the collection editor. This is why I use the
DesignTimeVisible(false). I also want my object to use a constructor with a
parameter that is why I use the TypeConverter. When I set the
DesignTimeVisible to False the TypeConverter never gets called. Does anyone
know how to make this work??

Thanks for the help
