BaseFilter fails to recognize non-faces resource requests, invoking BaseXMLFilter.doXmlFilter() ----------------------------------------------------------------------------------------------- Key: RF-1360 URL: http://jira.jboss.com/jira/browse/RF-1360 Project: RichFaces Issue Type: Bug Affects Versions: 3.1.3 Environment: Richfaces 3.1.3 (cvs), Seam 2.0.1 (cvs), Jboss 4.2.2 Reporter: Stuart Robertson Assigned To: Tsikhon Kuprevich Priority: Critical Fix For: 3.2.0 When servicing a non-jsf request, in this case to stream a pdf down to the user, the BaseFilter is mangling the contentType by appending an incorrect char encoding onto the (correct) content type. 13:58:28,313 INFO [FileServlet] Streaming file About Stu.pdf, contentType application/pdf and size 94171 to browser... 13:58:28,371 ERROR [STDERR] java.lang.Exception: contentType set to application/pdf;charset=ISO-8859-1 13:58:28,371 ERROR [STDERR] at org.jboss.seam.servlet.SeamFilter$FilterChainImpl$1.setContentType(SeamFilter.java:66) 13:58:28,371 ERROR [STDERR] at javax.servlet.ServletResponseWrapper.setContentType(ServletResponseWrapper.java:130) 13:58:28,371 ERROR [STDERR] at org.jboss.seam.servlet.SeamFilter$FilterChainImpl$1.setContentType(SeamFilter.java:65) 13:58:28,371 ERROR [STDERR] at org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:260) 13:58:28,371 ERROR [STDERR] at org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:281) 13:58:28,371 ERROR [STDERR] at org.jboss.seam.web.Ajax4jsfFilter.doFilter(Ajax4jsfFilter.java:60) And in BaseFilter, doXmlFilter is always invoked because the if condition is for "true". Here is the code from BaseFilter starting on line 271: // check ajax request parameter // TODO - check for JSF page. if (true) { if (log.isDebugEnabled()) { log.debug(Messages .getMessage(Messages.FILTER_XML_OUTPUT)); } // Execute the rest of the filter chain, including the // JSP xmlFilter.doXmlFilter(chain, httpServletRequest, httpServletResponse); doXmlFilter() appends an incorrect charType to a resource mimetype (in this case "application/pdf"). The correct behavior, if I read the code correctly, would be to invoke chain.doFilter() for resource requests. I think the key is in the TODO. The code needs to recognize when the request is outside of faces, and not interfere with the response headers at that point.
