[Zope] problem with dtml-in and Zope 2.2

[Chris McDonough]

First of all, make sure you don't try to define classes that should be
persistent in an external method... it wont work the way you expect it
to.

Second (untested):

def getRecords(self):
    """ """
    class record:
        __allow_access_to_unprotected_subobjects__ = 1 
        # this may be unnecessary?
        pass

    r = record().__of__(self)
    r.height = '25'
    return [r]
