Events fired by <a4j:ajax>?

[peter.falken]

I'm using RichFaces 4.3.1 on JBoss AS 7.1

We have an <a4j:commandButton> that uses an <a4j:ajax> to call a listener.

Can some one help me understand if it is possible to re-write the code in cleaner fashion or I might be miss-understanding that <a4j:ajax> doesn't fire events.

The original code (this works):

<a4j:commandButton value="Cancel" immediate="true">
          <a4j:ajax listener="#{serviceManager.refresh}" oncomplete="#{rich:component('popup')}.hide(); return false;" />
</a4j:commandButton>

This doesn't work - but looks cleaner:

<a4j:commandButton value="Cancel" immediate="true">
          <a4j:ajax listener="#{serviceManager.refresh}">
                    <rich:componentControl event="complete" target="popup" operation="hide" />
          </a4j:ajax>
</a4j:commandButton>

This doesn't work either - but looks cleaner:

<a4j:commandButton value="Cancel" immediate="true">
          <a4j:ajax listener="#{serviceManager.refresh}">
                    <rich:componentControl event="oncomplete" target="popup" operation="hide" />
          </a4j:ajax>
</a4j:commandButton>

Hi,

a4j:ajax does not create a DOM element so there are no DOM events to be fired from it.

That said, what's "unclean" about the first example? No reason for writing 10 lines of code if you can do it in one.

Thanks Michal, for clearing my doubt.

Regarding the "unclean" code, I would say that the two last examples are a bit more elegant & readable - I guess it is question of style more than of functionality.
