[Zope-CMF] DEV: _morphSpec

[alan runyan]

erm. it seems the default for contentValues() spec argument
is suppose to be meta_type's not portal_types.  this could
easily be changed in _morphSpec().  when it called
portal_types its saying filter using meta_type's only.  

Is this really desired default behavior?  This means all
"repurposed" content could only be queried by passing
the meta_type and then doing extra filtering.  

I would propose that we call listContentTypes() with
no arguments.
