> When there is more than one ajax component on a page, the client somtimes freezes. It seems that if there is more than one request in the queue, the system will stop working (no submit possible). The last debug message is "Request queued!", which seems to come from the following code in tobago.js:
> Tobago.Transport = {
>   requests: new Array(),
>   pageSubmited: false,
>   request: function(req, submitPage) {
>     if (submitPage) {
>         this.pageSubmited = true;
>         this.requests.push(req);
>     } else if (!this.pageSubmited) {
>       this.requests.push(req);
>     } else {
>         return;
>     }
>     if (this.requests.length == 1) {        <--------------------------- maybe this is the problem. What about "this.requests.length > 0" ?
>       LOG.debug("Execute request!");
>       this.requests[0]();
>     } else {
>       LOG.debug("Request queued!");
>     }
>   },
>   requestComplete: function() {
>     this.requests.shift();
>     LOG.debug("Request complete! Queue size : " + this.requests.length);
>     if (this.requests.length > 0) {
>       LOG.debug("Execute request!");
>       this.requests[0]();
>     }
>   }
> }
