            Description

            In older IE browsers, when the dataExporter button is clicked a new window is opened which facilitates the download of the file. Upon clicking the "Close Window" button an NPE is thrown in the server logs:

            java.lang.NullPointerException
            at java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.java:89)
            at org.icefaces.ace.component.dataexporter.ExporterResource.getInputStream(ExporterResource.java:47)
            at org.icefaces.application.ResourceRegistry.handleResourceRequest(ResourceRegistry.java:152)
            at org.icefaces.impl.application.WindowScopeManager.handleSessionAwareResourceRequest(WindowScopeManager.java:69)
            at org.icefaces.impl.application.SessionAwareResourceHandlerWrapper.handleResourceRequest(SessionAwareResourceHandlerWrapper.java:40)
            at javax.faces.application.ResourceHandlerWrapper.handleResourceRequest(ResourceHandlerWrapper.java:125)
            at org.icefaces.impl.application.SessionTimeoutMonitor.handleSessionAwareResourceRequest(SessionTimeoutMonitor.java:71)
            at org.icefaces.impl.application.SessionAwareResourceHandlerWrapper.handleResourceRequest(SessionAwareResourceHandlerWrapper.java:40)

            This doesn't seem to have a function impact. Also if using the windows close button instead of the link, this issue isn't seen.

              Attached test case that reproduces the issue.

              Steps:

              • Load welcomeICEfaces.jsf in IE8 or IE7.
              • Click the Export button.
              • A new window is opened, click the link to download the file.
              • Save or cancel the download and click the Close Window link.

              Note: With Tomcat, the error doesn't get displayed in the main server logs but is shown in the localhost log file.

              Committed fix to trunk at revision 33072. Prevented the default behaviour of the anchor element, in order to avoid sending another resource request when clicking the link to close the window.
