--------------------------------------------

Could you give me a example? Would be great if you can fork https://github.com/primefaces/primefaces-test, so i can compare different impls and versions

> When i decode component parameter value is not available in requestParameterMap.

>  
> {code:java}
> Map<String,String> paramMap = facesContext.getExternalContext().getRequestParameterMap();
> // this works in 2.2.8
> String myParamValue = paramMap.get("my_param"); // null
> // in 2.3-next parameters are wrapped in params
> String paramValue = paramMap.get("params"); // [object Object]{code}
> This is because the paramater is wrapped in params in AjaxScriptBuilder.
>  
> {code:java}
> params: {
>   my_param: my_value
> }
> {code}
> During parameter processing in the jsf send method, the encodeURIComponent(val) is called, where var is just 'my_param: "my_value"'. The result of this method is '[object=Object]'.
>  
> If I locally canceled the wrapping of parameters in AjaxScritBuilder into params, then everything started working again as in my old MyFaces version 2.2.8.
