Hi,
  I read the documentation and it briefly mentions SingleJoin, but gives
no example. 

I tried to use ForeignKey in the referenced class and SingleJoin in the
primary class, but I get this error when retrieving.

AttributeError: DataRow instance has no attribute 'processRowID'

My classes are simple.

class DataRow(SQLObject):
     type = StringCol()
     data  = BLOBCol(length=2**24)
     text = UnicodeCol()
     row = ForeignKey('ProcessRow')

class ProcessRow(SQLObject):
     path = StringCol()
     status = StringCol()
     data = SingleJoin('DataRow')

r = ProcessRow(path='here',status='loading')
datar=DataRow(data=d,type='binary',text='',row=r)

I'm not sure how to set the 'data' attribute for a ProcessRow since
both classes refer to each other. The DataRow SQL entry has a correct
row_id column set, but when I try to read it back like this, gives
error.

    r = ProcessRow.get(1)
    print "STATUS:"+r.status
    print "DATA:"+r.data.type   <<<<< generates error


thank you.
Darren
