Thomas Andraschko commented on MYFACES-4346:
--------------------------------------------
AFAICS it worked in 2.3 but i refactored the whole code for 2.3-next.
However, it seems that Mojarra does the same.
So is it ok for you to close it as won't fix and aligned with Mojarra?
> The ClientBehaviorContext.Parameter is not available from requestParameterMap
> -----------------------------------------------------------------------------
>
> Key: MYFACES-4346
> URL: https://issues.apache.org/jira/browse/MYFACES-4346
> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.3-next-M2
> Reporter: Jan Krpata
> Priority: Major
>
>
> The ClientBehaviorContext.Parameter is not available from requestParameterMap.
>
> This is part of my component renderer.
>
> {code:java}
> public String onclick(UIComponent component, FacesContext context) {
> Collection<ClientBehaviorContext.Parameter> paramList = new ArrayList<>();
> paramList.add(new
> javax.faces.component.behavior.ClientBehaviorContext.Parameter("my_param",
> "my_value"));
> Map<String, List<ClientBehavior>> behaviors = ((ClientBehaviorHolder)
> component).getClientBehaviors();
> String onclick = ClientBehaviorRendererUtils.buildBehaviorChain(context,
> component, component.getClientId(), ClientBehaviorEvents.CLICK, paramList,
> ClientBehaviorEvents.ACTION, paramList, behaviors, null , null);
> return onclick;
> }
> {code}
> 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.
