[Zope3-Users] Five Formlib and validator

[Jesper Petersen]

Hi Christian,I can see you are using Zope2/Five/Plone so I'm not sure how
well my answer applies, but I'll answer anyway :)
I got a similar form working just fine in Zope3. It could be that you are
using a named template implementation and you forgot to display the
view/error_views

If so, you need to have something like this in the page template to actually
display the error..

        <div class="form-status" tal:condition="view/status">
            <div class="summary" tal:content="view/status">
               Form status summary
            </div>
            <ul class="errors" tal:condition="view/errors">
               <li tal:repeat="error view/error_views">
                  <span tal:replace="structure error">Error Type</span>
               </li>
            </ul>
        </div>
