Can you double check that it is actually the default value, and not a
trailing empty line (I'm guessing that you are posting to 'addTeacher'
from a form with a control like: '<textarea
E.g, change the 'teachers:list:default' value to some other string, and
see if that value propagates.
Either way, as a robustness measure I would recommend adding some input
checking to 'addTeacher', e.g.:
def addTeacher( self, teachers ):
""" Add one or more teachers.
teachers = filter( None, teachers ) # strip empty lines
# your processing here
