8 NOTE: DEPRECATED: You can also leave the ID BLANK to show all errors. But this has been deprecated b/c we need the ID to make AJAX updating work.
* NOTE: to show errors on WFDynamic-generated widgets, use WFShowErrors with the ID of the WFDynamic. The WFShowErrors tag must occur AFTER the WFDynamic tag.
*
* @param array The params from smarty tag.
* @param object WFSmarty object of the current tpl.
* @return string The rendered HTML of the error.
* @todo Need to make it not-hard-coded to get the form_error.tpl file... should be able to override this in userland.
