I've created <https://javaserverfaces-spec-public.dev.java.net/issues/show_bug.cgi?id=7...;, target for 2.1 (not 2.0 Rev a) AS> ViewDeclarationLanguage implementation close depended from AS> ViewHandler implementation. [...] AS> modifications. Possible solutions are: AS> 1) Introduce ViewDeclarationLanguage#writeState method that should AS> be called from ViewHandler#writeState in the same way as renderView AS> method does. AS> 2) Change default ViewHandler#renderView method requirements that it AS> should create appropriate ResponseWriter before calling AS> ViewDeclarationLanguage#renderView method, so ViewHandler can AS> perform late state writing in consistent way. AS> I prefer to the #2 solution because that allows to reduce duplicated AS> code in the ViewDeclarationLanguage implementations, but there is a AS> problem: VDL may provide additional options for response like buffer AS> sixe, encoding and content type that required to create AS> ResponseWriter. Possible solution is to make public AS> ViewDeclarationLanguage#createResponseWriter(FacesContext context) AS> method that already exists in the Mojarra implementation. As you know, ultimate responsibility for creating the ResponseWriter lies with the RenderKit. Is it fair to describe your requirement like this: we need a standard way for the VDL to decorate the ResponseWriter at the beginning of the rendering phase? If so, the VDL could listen for the PreRenderView event and perform the decoration there. Would that work?
