[seam-issues] [JBoss JIRA] (JBSEAM-5093) Seam produces malformed partial response on ViewExpiredException with Ajax

Marek Schmidt created JBSEAM-5093: ------------------------------------- Summary: Seam produces malformed partial response on ViewExpiredException with Ajax Key: JBSEAM-5093 URL: https://issues.jboss.org/browse/JBSEAM-5093 Project: Seam 2 Issue Type: Bug Components: Core Affects Versions: 2.3.0.Final Environment: Seam 2.3.1-SNAPSHOT 2013-05-02 082f3b3459893b1c4200b7bd8ce99556f87f0dd0 Reporter: Marek Schmidt Assignee: Marek Novotny When ViewExpiredException occurs in an Ajax request, the response is malformed, containing duplicate partial-response element. This results in the response not being parsed (and in this case, redirect not being followed). {noformat} <?xml version='1.0' encoding='UTF-8'?> <partial-response><redirect url="/seam-booking/home.seam?cid=22"></redirect></partial-response><?xml version="1.0" encoding="UTF-8"?> <partial-response><redirect url="/seam-booking/home.seam?cid=22"/></partial-response> {noformat} This seems to happen, because there are two rules for the redirection in pages.xml: - main.xhtml has login required, handled in Pages.redirectToLoginView() <page view-id="/main.xhtml" login-required="true"> - exception handler for ViewExpiredException, handled in ExceptionFilter <exception class="javax.faces.application.ViewExpiredException"> <redirect view-id="/home.xhtml"> ... </exception> None of the Seam's components involved (ExceptionFilter, Pages, Exceptions, RedirectHandler, MockExternalContext, ... ?) checks whether the response has already been written and the redirect partial response gets written twice. -- This message is automatically generated by JIRA.
