I got a error from myfaces: 10:18:34 ERROR - org.apache.myfaces.renderkit.html.util.ReducedHTMLParser:653 - Malformed end tag at line 41; skipping p arsing I want separate my download-function (rich:htmlCommandlink) which returns a xml-file from the rest of my application/ui. It should doesn't matter which other components used on the page with the download-link. The download-bean reset the faces-response and return a none-faces-xml-content ... exists a "Best Practice" for such a scenario? > > If for some reason you really care, then you can switch to using the > StreamingAddResources implementation rather than the > DefaultAddResources > one.
