Re: NPE in TagUtils.getStack after upgrading to 2.0.1
>Root cause follows. >java.lang.NullPointerException >at org.apache.struts2.views.jsp.TagUtils.getStack(TagUtils.java:56) I had this problem intermittently, and finally figured out its source and how to quash it for good. It has to do with when struts2 "cleans up" after itself to prevent memory leaks (after which the ValueStack is gone, thus NPE). Check the order of your filter stack. If you add a struts-cleanup filter you can determine where in the stack processing struts2 does this. http://struts.apache.org/2.x/struts2-core/apidocs/org/apache/struts2/dispatcher/ActionContextCleanUp.html -Dale -- View this message in context: http://www.nabble.com/Re%3A-NPE-in-TagUtils.getStack-after-upgrading-to-2.0.1-tf2708127.html#a7724423 Sent from the Struts - User mailing list archive at Nabble.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: NPE in TagUtils.getStack after upgrading to 2.0.1
Thanks for the respone. I'm using the xwork-2.0-beta-1.jar that was included in the struts 2.0.1 beta distribution. Unfortunately, that jar file doesn't contain the org.apache.struts2.views.jsp.TagUtils class. For that, I've included the struts2-all-2.0.1.jar file in my webapp. Has anyone successfully used the struts 2 taglibs in a struts 1 app? - Original Message From: Martin Gainty <[EMAIL PROTECTED]> To: [EMAIL PROTECTED]; user@struts.apache.org Sent: Sunday, November 26, 2006 2:15:19 PM Subject: Re: NPE in TagUtils.getStack after upgrading to 2.0.1 Jon- http://jira.opensymphony.com/secure/IssueNavigator.jspa?view=rss&&pid=10050&fixfor=21200&tempMax=25&reset=true&decorator=none reported a bug with OpenSymphony 1 beta2 getStack method which was patched in version 1.0 Can you verify your OpenSymphony and or Xwork version?
