> I've been shown some problems lately with MyFaces 1.0.9 and ADF Faces.
> The problems specifically trace to MyFaces's use of
> ResponseWriter.endDocument() to output Javascript.  Since ADF Faces
> runs with its own RenderKit (and therefore its own ResponseWriter),
> this Javascript is getting dropped and not written.
> I'd recommend (both as JSF EG guy and ADF Faces guy) that this MyFaces
> code be moved *out* of ResponseWriter.endDocument().  Specifically:
> - ResponseWriter.endDocument() is not guaranteed to be called before
> the close of  or even the close of , and therefore this
> script cannot be safely output at this point.  It's quite likely that
> changes in JSF 1.2 will essentially guarantee that endDocument() is
> not called until the close of all output.
> - This is not really the intent of ResponseWriter.endDocument().  In
> HTML, it should be a no-op.  It's there for more bizarre scenarios
> like a ResponseWriter outputting a SOAP envelope around a response.
> - It's breaking ADF Faces. :)
> A significantly cleaner way to output needed Javascript is to add it
> as needed from the Renderers that require it (using a request-scoped
> attribute to track if its been added already).
