[Zope3-Users] z3c.form: Howto include validation errors into a custom pagetemplate?

[Peter Piehler]

Hello,

i have a  spreadsheet like z3c.formdemo spreadsheet.
I copy and paste
        <ul class="errors"
            tal:condition="view/widgets/errors"
            metal:define-macro="errors">
          <li tal:repeat="error view/widgets/errors">
            <tal:block condition="error/widget">
              <span tal:replace="error/widget/label" />:
            </tal:block>
            <span tal:replace="structure error/render">Error Type</span>
          </li>
        </ul>
from formui.table-form.pt into my pagetemplate. "view/widgets/errors" 
seems to be empty but validation error occurs.
What should i do to display validation errors?

Regards,
Peter
