[Zope] Recursive Calling the same DTML Method is not validated?

[iap@y2fun.com]

Well, I answer myself:
change the lib/python/OFS/DTMLMethod.py in line 203:
from
    del self.__dict__['validate']
to
    if self.__dict__.has_key('validate'): del self.__dict__['validate']
Then, it works again.
But maybe this is just a skin-deep solution.
I have no idea if this will cause another problem, such as security hole?
