> I've got a {{a4j:commandButton}} which {{render}} itself and is {{rendered}} if the number of time I've clicked on it is less than 1.
> The problem is that when I click twice on it very quickly, then I've got a "Uncaught TypeError: Cannot read property 'name' of null" from {{jsf.js.xhtml}} and then no more AJAX query can be sent from the UI (all the {{a4j:commandButton}} for example do nothing more), and the status is frozen to the {{start}} facet (my progress.gif is never hidden because neither {{onstop}} nor {{onerror}} methods are called).
> Here is the JS stack :
> {noformat}
> Uncaught TypeError: Cannot read property 'name' of null jsf.js.xhtml:1
> request jsf.js.xhtml:1
> richfaces.queue.submitFirstEntry richfaces-queue.js.xhtml:270
> richfaces.queue.onComplete richfaces-queue.js.xhtml:248
> sendEvent jsf.js.xhtml:1
> response jsf.js.xhtml:1
> richfaces.queue.response richfaces-queue.js.xhtml:413
> jsf.ajax.response richfaces-queue.js.xhtml:50
> onComplete jsf.js.xhtml:1
> req.xmlReq.onreadystatechange jsf.js.xhtml:1
> {noformat}
> I will attach test.xhtml & TestAction.java
