Tapestry: What's New

Release 2.2-beta-2

The ValidField now performs client-side validation of input. If a field is in error when the form is submitted, then an alert is displayed and the field is selected.

Begin making more use of OGNL expressions in place of Java code.

Malcom Edgar has contributed a DatePicker component.

Some more refactorings: IComponent methods addWrapped()/renderWrapped() -> addBody()/renderBody().

Tapestry documentation is now available in PDF format.

Release 2.2-beta-1

Tapestry has now replaced its simple property path support with the far more powerful Object Graph Navigation Library expressions. This promises to greatly extend the expressiveness of the specifications and further reduce the need for Java code. The property-path attribute of the <binding> element has been renamed to expression (this only affects the latest, 1.3, version of the DTD).

There are some small costs to using OGNL; the largest being a restriction in bean names, component ids and asset names. All of these must now be valid Java identifiers, and so cannot contain the dash ('-') character, which was previously permitted. This affects all specifications, including older versions.

Malcolm Edgar has lead the push to provide an excellent Tapestry Component Reference.

You can now control the exact location of a component template by declaring an asset named $template (which is not normally a legal asset name, due to the dollar sign). If such an asset exists, then it is used as the template.

A number of poorly named components have been renamed:

Action -> ActionLink
Direct -> DirectLink
InsertBlock -> RenderBlock
InsertWrapped -> RenderBody
Page -> PageLink
Service -> ServiceLink
ShowInspector -> InspectorButton
Text -> TextArea

Previous names will be maintained until at least release 2.3.

In addition, the documentation has been brought (largely) up to date with the significant changes so far in release 2.2.

Release 2.2-alpha-3

Tapestry now supports libraries, which can provide components, pages and engine services to an application. Libraries can also include libraries. The application specification has been ammended to include a new <library> element, and a new type of specification, the library specification, has been added.

Revamp how services construct and parse URLs. Rework service parameters to be typed objects, instead of simple strings (this is a change which may break some existing code).
