@BeginRender equivalent for component AJAX events

[Michael Prescott <mi...@gmail.com>]

I have a component that includes a zone - the zone is periodically
refreshed using the ZoneRefresh mixin.

Is there any equivalent to @BeginRender that I can use to set up data to
support the zone re-rendering?  @BeginRender methods are called when the
page renders, but they're not called when the zone re-renders via ajax.

The only event I've found that gets called is @PageAttached, but of course
this is deprecated.

Any tips would be appreciated!

Gratefully,

Michael

One note about ZoneRefresh mixin:

https://issues.apache.org/jira/browse/TAP5-2100

So it provides not the original event context(that was encoded in url) but
the context populated from parameter. And so it has no sence for now.

Far from being a gory detail, it's part of the public API for the mixin,
very similar to AutoComplete's "provideCompletions" event.

The mixin should ideally declare the event using @Events("refresh") and
should have a mention in the javadoc too.

Thanks, Lance, that looks like it will do the trick nicely.

Do you think that the 'refresh' event should be added to the ZoneRefresh
mixin's documentation?  Is this public/won't change, or a gory internal
detail?

The ZoneRefresh mixin fires the "refresh" event passing the (optional)
context parameter.

So, add a handler to the containing page / component.

Eg: void onRefresh(Foo context) {...}

If you return a Block, this will be rendered (zone.getBody() renders by
default).
