XWiki.AttachmentSelector does not work when Class has multiple Sheets bound

With two Sheets bound to a class to display separate view and edit page layouts the AttachmentSelector fails to set the uploaded file.
Sheet 1 has the 'edit' property set for the XWiki.SheetDescriptorClass object.
Sheet 2 has the 'view' property set for the XWiki.SheetDescriptorClass object.

It sends a redirect with a docAction=inline which doesn't display the correct layout.

eg:
http://localhost/wiki/bin/get/XWiki/AttachmentSelector?xaction=postUpload&docAction=inline&docname=PhotoLibrary.Albion&fieldname=PhotoLibrary.PhotoLibraryClass_0_planimage&form_token=7YE3OTmA62D8vFHztHrJ3Q

If I remove the 'edit' XWiki.SheetDescriptorClass object then the attachment selector works, but the correct 'view' Sheet is not used.

I worked around the default XAR import by doing the following:

I checked in the xaction=postUpload section of the XWiki.AttachmentSelector macro if the docAction was 'inline' and I changed it to 'edit' instead.
This then seems to work fine with both Sheets and the XWiki.SheetDescriptorClass set for both as appropriate.
