> jsf.js: Calling jsf.getViewState() with a direct reference to a form element

> Key: MYFACES-3178
> URL: https://issues.apache.org/jira/browse/MYFACES-3178
> Project: MyFaces Core
> Issue Type: Bug
> Components: General, JSR-314
> Affects Versions: 2.1.0, 2.1.1
> Environment: Client
> Reporter: Deryk Sinotte

> The jsf.getViewState() function is a standard part of the JSF client API.
> Currently, if I call this function with a valid reference to a form object,
> an exception is thrown. Firefox 4 (with Firebug) reports it as:
> this._onException is not a function
> I believe the problem stems from the getViewState implementation itself in
> Impl.js:
> getViewState : function(form) {
> /**
> * typecheck assert!, we opt for strong typing here
> * because it makes it easier to detect bugs
> */
> if (form) {
> form = this._Lang.byId(form);
> }
> if (!form
> || !form.nodeName
> || form.nodeName.toLowerCase() != "form") {
> throw new Error(this._Lang.getMessage("ERR_VIEWSTATE"));
> }
> var ajaxUtils = new myfaces._impl.xhrCore._AjaxUtils(0);
> var ret = this._Lang.createFormDataDecorator([]);
> ajaxUtils.encodeSubmittableFields(ret, null, null, form, null);
> return ret.makeFinal();
> },
> In that function, some checking is done to ensure that the form is a valid
> reference, then a new AjaxUtils is created with no parameters. Typically
> these would be warning and exception handlers. Since these handlers are
> missing, when encodeSubmittable fields runs into a problem and tries to use
> the handler, the above noted exception occurs.
> When encodeSubmittableFields is called, the form reference is set as the
> parameter expected for an individual form item and the parentItem is null. I
> believe the form should be set as the parent item:
> ajaxUtils.encodeSubmittableFields(ret, null, null, null, form, null);
> By setting it as the parent item, the encoding logic should be able to handle
> it correctly.
