An Update div within a Zone div (Tapestry 5.3 and earlier)
Deprecated |

_This feature is removed starting with Tapestry 5.4_ |
In many situations, a Zone is a kind of "wrapper" or "container" for dynamic content; one that provides a look and feel ... a bit of wrapping markup to create a border. In that situation, the Zone <div> may contain an update <div>.

Zone Effect Functions (Tapestry 5.3 and earlier)
Deprecated |
---|
_This feature refers to client-side logic only present in Tapestry 5.3 or earlier. For 5.4, there are client-side events that are triggered before and after changes to the Zone; listeners on those events can trigger whatever animations they like. |
...
The show and update function names (Tapestry 5.3 and earlier only) are converted to lower case; all the methods of Tapestry.ElementEffect should have all lower-case names. Because client-side JavaScript is so fluid (new methods may be added to existing objects), Tapestry makes no attempt to validate the function names ... however, if the names are not valid, then the default show and highlight methods will be used.
...
For examples of extending a Form with a Zone and updating multiple zones at once, see the Ajax Components FAQ.
There are also a number of Ajax-related examples at the Tapestry JumpStart site.
