Salvo Isaja commented on RF-13093:
----------------------------------
Here is a workaround that works on RichFaces 4.3.x and JSF 2.1 (tested on
RichFaces 4.3.4 on GlassFish 3.1.2.2 with Mojarra 2.1.23).
Include the following JavaScript after the standard jsf.js:
{code}
var origJsfAjaxResponse = jsf.ajax.response;
jsf.ajax.response = function response(request, context) {
var xml = request.responseXML;
var pr = xml.getElementsByTagName("partial-response")[0];
if (pr.children.length === 0) {
$(pr).append('<changes><update
id="javax.faces.ViewState">stateless</update></changes>');
}
return origJsfAjaxResponse(request, context);
};
{code}
If an empty partial-response is received, it just adds an update of the
stateless ViewState as it would happen with non-transient views. I've tested it
as is, but I suppose the "name" attribute would be more appropriate than "id",
depending on how the JSF implementations lays out the ViewState hidden.
This is not specific to rich:extendedDataTable but works around any case the
server returns an empty partial-response.

> Key: RF-13093
> URL: https://issues.jboss.org/browse/RF-13093
> Project: RichFaces
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: component-tables
> Affects Versions: 4.3.2
> Environment: GlassFish 3.1.2.2 with Mojarra 2.1.23
> Reporter: Salvo Isaja
> Labels: jsf22
> Fix For: 5.0.0.Alpha2
>
>
> When turning on transient (stateless) views in recent Mojarra versions (as
> per JSF 2.2 specification, to my best understanding), using request scoped
> backing beans, javax.faces.ViewState becomes the constant "stateless". Column
> resizing and reordering in extendedDataTable causes an Ajax request to the
> server, but in this case an invalid response is sent, containing only:
> {code:xml}
> <?xml version='1.0' encoding='UTF-8'?>
> <partial-response></partial-response>
> {code}
> This causes an exception in {{jsf.js}} because the partial-response element
> has no children and no further JavaScript processing happens in the view
> until the page is reloaded. In the non-transient view case, I see a
> {{change}} element updating only the ViewState is returned, instead.
> Other features seem to work pretty well in stateless mode, by the way.
> Thanks
