A common technique in Ajax applications is to Effect.highlight (yellow flash) items that change as a result of an Ajax operation. This example shows the use of AjaxHighlight to achieve this. AjaxHighlight provides a registery in which you can register objects that should be highlighted, then you can use an AjaxHighlight component (which acts much like a WOGenericContainer) passing it a value to match against. If the value for the AjaxHighlight component is in the highlight registry, it will be highlighted for you. For instance, in the example below, when you save a comment, the new comment object is put into the registry. In the list of comments, the <li> tags are actually AjaxHighlight containers that bind their value to the comment in the repetition. It's a lot harder to explain than it is to use :) Look at the example source, and I think it will make sense. Add a Comment:
