Re: Weird partial-response behavior with 2 partial-response tags
Hi,
Any news about this issue?
One developer from the primefaces-extensions team created an
ajaxErrorHandler and a PrimeFaces user would like to use this but the same
error occurs:

Hi,
it does not work in Mojarra, too.
Mojarra does not have handled or unhandles exception in my custom
ExceptionHandler.
So it would be an cool feature in MyFaces :)

Hi,
this "redirect-in-render-response-phase" works with Mojarra in both
caces (ajax, HTML request)?
We can fix it in myfaces. Spec mandates endDocument() in
ViewDeclarationLanguage.renderView(), but we can ignore it or find a
workaround for that.
