This
<hasBindErrors>
tag provides an Errors
instance in case of
bind errors. The HTML escaping flag participates in a page-wide or
application-wide setting (i.e. by HtmlEscapeTag or a "defaultHtmlEscape"
context-param in web.xml).
Attribute | Required? | Runtime Expression? | Description |
---|---|---|---|
htmlEscape | false | true | Set HTML escaping for this tag, as boolean value. Overrides the default HTML escaping setting for the current page. |
name | true | true | The name of the bean in the request that needs to be inspected for errors. If errors are available for this bean, they will be bound under the 'errors' key. |
