WebWork 2 : Release Notes - 2.1
This page last changed on Dec 14, 2004 by plightbo.
Key Changes
- JavaScript client validation support - not totally complete, but basic validators work well. Look at the validators.xml file include in src/example to see how you can configure your validators to do client side validation on top of their normal duties
- The label attribute in UI tags are no longer required
- The themes and templates in UI tags behave like they did in 1.x
- A new theme, in addition to the existing "xhtml" one, called "simple" is included that doesn't have any of the labels, error reporting, or table rows that the "xhtml" template has. This is more in line with the tags included with Struts.
- New UI tags for CSS styles and classes added: cssStyle and cssClass
- Old action!command URL support works again. This means you can invoke a doCommand() method like in 1.x
- ww:param tag no longer requires the name attribute (for ordered params, like with ww:text). It also evaluates the the body as the value if no value is given.
- UI tags now have access to the FormTag parameter map using the "form" key. This means $parameters.form.name would return the form name, for example. The result is that complex JavaScript-based components can be built.
