[ZPT] formating validation results

First better try not to do a redirect, but return the page directly;
if You use a redirect You can only pass the error dictionary as a string.

Saying:

  context.REQUEST.set('formErrors', error)
  context.REQUEST.set('value2', value2)
  return context.show_zpt()

should call the page directly and allow to pass the dictionary as is.
Alternatively You can say

   return context.show_zpt(formErrors=errors, value2=value2)

and then get the parameters via options/formErrors instead of request/formErrors.
(unless I am mistaken here.)

Yow: when passing in the errors dictionary directly, You should be able to say something like:

    <div tal:condition="options/formErrors|nothing">
        <h3>Form validation errors</h3>
        <dl tal:define="errors options/formErrors">
          <tal:block repeat="err errors/keys">
            <dt tal:content="err" />
            <dd tal:content="python:errors[err]" />
          </tal:block>
        </dl>
     </div>

The details depend on Your data structure, of course.

  Most probably You want to loop over the fields of Your form and check
if there is an error for the given field, so the errors appear in the same order
and the fields (the order is pretty undefined for the dictionary ...)
