Custom destination component appears in "Common" SSIS Toolbox rather than "Other Destination"

In SQL 2012 after my custom destination component is installed it appears under the "Common" category in the Toolbox rather than "Other Destinations". Is that the new way SQL 2012 Data Tools works or am I missing an extra setting in my code? My component is defined to be a DestinationAdapter:

    [DtsPipelineComponent(DisplayName = "My Destination",
                          Description = "some description",
                          CurrentVersion = COMPONENT_META_DATA_VERSION, 
                          ComponentType = ComponentType.DestinationAdapter)]

    public class DestinationComponent : PipelineComponent
    {
        // ...etc...
    }

Thanks for any help on this.
