[Zope] TALES on-error

[drew nichols]

Can anyone help ?

I understand from the TAL documentation that the on-error tag sets a var 
error.
<<<
##bind namespace=_
...

error = _['error']
print error.type
print error.value
print error.traceback

return printed
 >>>

Unfortunately the error produced says that:

ErrorInfo instance has no attribute 'traceback'


Checking the Tales.py i agree. It doesn't.
type and value are fine, but how do i get the traceback?????
