    Tomcat exception Cannot call sendError() after the response has been committed

    paperno3 Level 1

      CF 10 Developer Edition.


      Windows XP SP3


      When submitting a page that worked fine in CF 7 on this machine, I get an error I've never seen before:



      HTTP STATUS 500-


      description: The server encountered an internal error () that prevented it from fulfilling this request.




      javax.servlet.ServletException: ROOT CAUSE: java.lang.IllegalStateException: Cannot call sendError() after the response has been committed at org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:451) at javax.servlet.http.HttpServletResponseWrapper.sendError(HttpServletResponseWrapper.java:1 20) at coldfusion.tagext.io.cache.ehcache.GenericResponseWrapper.sendError(GenericResponseWrappe r.java:91) at coldfusion.filter.FormScope.parseQueryString(FormScope.java:501)

      Totally puzzled,
