Summary: No intermidiate table crated with one way RelatedJoin

Initial Comment:
I'm using SQLObject-0.7.1dev_r1675-py2.4.egg with
Turbogears 0.9a6

When running tg-admin sql (sql|create) I get notice the
following misfeature:

RelatedJoin intermediate tables are only created when
the table with the "lowest sorted" name is processed
even if only the "highest sorted" name has a RelatedJoin.

class File(SQLObject):
    filename = UnicodeCol()
    fileType = StringCol()
    sha1HexDigest = StringCol(length=40, alternateID=True)
    # NO related join here!

class Project(SQLObject, HelperClassNotSqlObject):
    class sqlmeta:
        # Force SQLObject to create the intermediate
        # project_dumb_file table when looking at our
project
        # files RelationalJoin instead of waiting to 
        # create it until it finds the projects
RelationalJoin
        # in DumbFile (which dows not exist). Our table
must
        # be lexiographically smaller than DumbFile
        # a < d   ->  aproject < dumb_file
        table = "aproject"
        _defaultOrder = 'projectNumber'
        
    projectNumber = StringCol()
    files = RelatedJoin("File")
    description = UnicodeCol(default="")

I do not want a relation from file to project because
many classes has files and I do not want File to have
relations to all these classes when looking at classes
related to a file is not needed but looking at files
related to a project is wery much needed.

Okay, it seems I was optimistic when renaming only the
table. Actually the class has to be renamed, but this breaks
with the following error:

And, I have no intention of renaming Project to aProject
anyway ...
