> Problem: validation errors returned from the server can not be inserted into
> the page content.
> StrutsUtils.showValidationErrors in utils.js tries to detect the theme that
> is being used for the form by checking to see if the first child node of the
> form is a table node (line 53). If you have a hidden form field, the first
> child node is actually the hidden field, so the code thinks you are using the
> css_xhtml theme and fails to report validation errors within the page
> correctly - instead it pops up a Javascript alert indicating: "Could not
> validate: form_user_firstName".
> JSP Code:
> <s:form method="post" namespace="/nodecorate" action="mysettings_update"
> theme="xhtml" id="form">
> <s:textfield key="user.firstName" />
> <s:textfield key="user.lastName" />
> <s:textfield key="user.emailAddress" />
> <s:hidden name="user.version" />
> <sx:submit validate="true" ajaxAfterValidation="true" targets="response"
> showLoadingText="false" />
> </s:form>
> A workaround is to make the hidden field part of the table:
> <tr style="display:none"><td colspan="2"><s:hidden name="user.version"
> /></td></tr>
> In addition to the above, it would also be good if addErrorCSS() in
> css_xhtml/validation.js could actually report the error if it cannot figure
> out the layout of the page. See line 83-45.
