[Zope] Transaction rollback

[Luiz Fernando B. Ribeiro]

I need to return an error page with instructions after verifying a 
request but I need to do a rollback. How can I call a full rollback, 
like when using raise(), inside a python script and redirect to an error 
page.

I found many posts about get_transaction().rollback() but it is 
deprecated in Zope 2.9. What is the modern way of doing this?

Thanks in advance.
