[Boost-build] Problem using cast

I have created a generator that transforms a file into a CPP file via sed.
I am able to get the process to run end to end if my generator has a unique 
type
suffix registered (e.g. type.register CUSTOMERINFO : cpp_to_sed : CPP ;)

However, I want to get this working without having to change the source 
files,
only the build system.  The name of the file that I want to run through sed 
is
defaultcustomerinfo.cpp.  This seems to be a problem since CPP is already a
registered type.

I tried to register the type with no suffix (type.register CUSTOMERINFO : : 
CPP
;) and use a cast to make my generator be invoked:

cpp customerinfo.cpp
    : # sources
        [ cast _ CUSTOMERINFO : defaultcustomerinfo.cpp ]
        #defaultcustomerinfo.cpp_to_sed
    ;

But I get a missing argument error when I try this:

C:/bin/buildtools/boost-build/kernel\class.jam:92: in new
*** argument error
* rule object(cast-target-class)@77.__init__ ( name : project : type : 
sources *
: requirements * : default-build * : usage-requirements * )
* called with: ( _ : object(project-target)@69 :  : defaultcustomerinfo.cpp 
:
object(property-set)@29 : object(property-set)@32 : object(property-set)@8 : 
:)
* missing argument type
C:/bin/buildtools/boost-build/tools\cast.jam:38:see definition of rule
'__init__' being called
C:/bin/buildtools/boost-build/tools\cast.jam:78: in cast

Thinking maybe I just called cast wrong, I changed my invocation to:
[ cast _ : CUSTOMERINFO : defaultcustomerinfo.cpp ]

But that only changes the missing argument error to be in cast instead of 
__init__:
..\..\..\..\engine\cpp\util\common\Jamfile:24: in modules.load
*** argument error
* rule cast ( name type : sources * : requirements * : default-build * :
usage-requirements * )
* called with: ( _ : CUSTOMERINFO : defaultcustomerinfo.cpp )
* missing argument type
C:/bin/buildtools/boost-build/tools\cast.jam:69:see definition of rule 
'cast'
being called

Is there something simple I'm doing wrong?
