[jira] Updated: (WW-2240) FileUploadInterceptor causes null pointer exception

["Benjamin McCann (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/struts/browse/WW-2240?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Benjamin McCann updated WW-2240:
--------------------------------

    Attachment: improvedLogging.patch

Please at least wrap the log call so that the file upload interceptor can be used on most logging levels before 2.1.4.  I'd commit the fix myself if I had svn access.  I know this patch does not fix the root issue, but it's not a bad thing to do anyway for performance reasons.  And more importantly, this is a pretty serious bug and a 2.1.1 release should include a fix at the very least for the logging issue which would at least provide a workaround of downgrading the log level for this interceptor.

> Using struts2-core-2.1.0-SNAPSHOT-20071003.jar, I received the following:
> java.lang.NullPointerException
> 	at org.apache.struts2.interceptor.FileUploadInterceptor.intercept(FileUploadInterceptor.java:277)
> 	at com.opensymphony.xwork2.DefaultActionInvocation$1.doProfiling(DefaultActionInvocation.java:229)
> 	at com.opensymphony.xwork2.DefaultActionInvocation$1.doProfiling(DefaultActionInvocation.java:228)
> 	at com.opensymphony.xwork2.util.profiling.UtilTimerStack.profile(UtilTimerStack.java:455)
> 	at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:226)
> My action was able to access the File, so it must have been something in the cleanup.  My action was very similar to the one found in this tutorial http://www.roseindia.net/struts/struts2/struts-2-file-upload.shtml
