Om problemen met de zgn. View-State van de pagina of sommige formulieren te voorkomen, worden AJAX-verzoeken geserialiseerd.
JSF-Extensions (https://www.intersult.com/wiki/page/JSF%20Ext) gives you the option to parallelize AJAX requests. Just set the JavaScript variable jsf.ajaxQueue to another value than the default of 1. But if you don't lock out manually duplicate requests from within the same form or rendering of the same region, you will get errors.
Zo activeer je parallelle verzoeken:
<script type="text/javascript">
if (jsf)
jsf.ajaxQueue = 2;
</script>
For example you can parallelize the rendering on the server of a page with . Most applications would not need parallel requests, because they run nice when strictly serialized.
