How to conditional process action in JSF?

If validation failed, it should have a way to decide what action to do:

@Common JSF

<a4j:commandButton ... oncomplete="if (#{!facesContext.validationFailed}) $('#dialog_id').dialog('close')" />

@Primefaces

<p:commandButton value="submit" oncomplete="if (args &amp;&amp; !args.validationFailed) dialog.show()" process="@this"/>

</tr>
</table>
