I try to validate a formulator object with a python script If an error was submitted the python script would acquire again the zope page template that render the formulator with the error messages

This question is probably better suited to the zope@zope.org list...

My problem is than when I try to return the ZPT render Zope process the return and convert <, > and & to the < > and &

I try to conver these codes, change the content-type and so on but the problem persists
