Hi,
I've found a solution: overriding the AjaxPartialResponseRenderer service.
In my module class I put this:
public static void bind(ServiceBinder binder) {
binder.bind(AjaxPartialResponseRenderer.class,
StbAjaxPartialResponseRenderer.class).withId("StbAjaxPartialResponseRenderer");
}
public static void
contributeAliasOverrides(Configuration<AliasContribution<?>> configuration,
@InjectService("StbAjaxPartialResponseRenderer")
AjaxPartialResponseRenderer aprr) {
configuration.add(AliasContribution.create(AjaxPartialResponseRenderer.class,
aprr));
}
And here is my StbAjaxPartialResponseRenderer class:
public class AminoAjaxPartialResponseRenderer implements
AjaxPartialResponseRenderer {
private final MarkupWriterFactory factory;
private final Request request;
private final Response response;
private final PartialMarkupRenderer partialMarkupRenderer;
private final String outputEncoding;
public AminoAjaxPartialResponseRenderer(MarkupWriterFactory factory,
Request request,
Response response,
PartialMarkupRenderer
partialMarkupRenderer,
@Inject
@Symbol(SymbolConstants.CHARSET)
String outputEncoding) {
this.factory = factory;
this.request = request;
this.response = response;
this.partialMarkupRenderer = partialMarkupRenderer;
this.outputEncoding = outputEncoding;
}
public void renderPartialPageMarkup() throws IOException {
// This is a complex area as we are trying to keep public and
private services properly
// seperated, and trying to keep stateless and stateful (i.e.,
perthread scope) services
// seperated. So we inform the stateful queue service what it
needs to do here ...
ContentType pageContentType = (ContentType)
request.getAttribute(InternalConstants.CONTENT_TYPE_ATTRIBUTE_NAME);
C*ontentType contentType = new ContentType("text/plain",
outputEncoding);
// The original was: ContentType contentType = new
ContentType(InternalConstants.JSON_MIME_TYPE, outputEncoding);*
MarkupWriter writer = factory.newPartialMarkupWriter(pageContentType);
JSONObject reply = new JSONObject();
// ... and here, the pipeline eventually reaches the PRQ to let it
render the root render command.
partialMarkupRenderer.renderMarkup(writer, reply);
PrintWriter pw = response.getPrintWriter(contentType.toString());
pw.print(reply);
pw.flush();
}
}
This is the exact copy of the internal service class
AjaxPartialResponseRendererImpl except one line.
This solution works but I should not override an internal service,
because if i upgrade to a new version and this service changes, my code
won't work.
Any better solution for my problem? I would appreciate any answer.
Thank you, Zsombor

Hi All!
I would like to change the content-type of the ajax response, when
rendering a component from an ajax request.
The content-type is 'application/json' and it need to be 'plain/text'.
We develop an ip-tv middleware and the setTopBox's browser (Opera
gogi) can not understand the application/json content-type (I think it
treats the response as binary data). I handle the ajax response with
my own javascript code, so 'plain/text' would be fine.
I see from the source code that the mime-type's hard coded at the
InternalConstants.JSON_MIME_TYPE variable, so i don't know how to
change it.
Anyone has idea how to accomplish this?
