 Description  « Hide
Whenever I try to see the Full Content view on the issue navigator, I get the following exception. It seems to occur on every filter I've tried. Tomcat's catalina.out log shows nothing.

Kenny,

Could you please try shutting down Tomcat, deleting Tomcat's work/ directory and restarting? The JSP compiler may have gotten confused, perhaps during an upgrade.

If this doesn't help: can you identify any specific issue displaying that triggers this?

If you could look in the work/ directory and locate the file mentioned in the stacktrace, navigator_0002dfull$jsp.java, then we can see exactly where in the JSP it's breaking and probably identify the cause.

Cheers,

--Jeff

Hi Jeff,

I tried shutting down tomcat and deleting the contents of work/ as suggested, but the error still occurs.

Also, the problem seems to occur regardless of which issues are present in the navigator, so I don't think the problem is being triggered by specific issues.

I had a look at the navigator_0002dfull$jsp.java file to locate the position of the error. I'll attach the complete file, but here is the code leading up to the problematic line:

// begin [file="/secure/views/navigator/navigator-full.jsp";from=(129,4);to=(129,85)]
/* ---- webwork:bean ---- */
webwork.view.taglib.BeanTag _jspx_th_webwork_bean_2 = new webwork.view.taglib.BeanTag();
_jspx_th_webwork_bean_2.setPageContext(pageContext);
_jspx_th_webwork_bean_2.setParent(_jspx_th_webwork_iterator_0);
_jspx_th_webwork_bean_2.setName("'com.atlassian.jira.web.util.FileSize'");
_jspx_th_webwork_bean_2.setId("sizeFormatter");
try {
int _jspx_eval_webwork_bean_2 = _jspx_th_webwork_bean_2.doStartTag();

The NPE is thrown whilst doing a pageContext.setAttribute() inside the doStartTag() method:

if(getId() != null)
{
pageContext.setAttribute(getId(), bean);

Since getId() can't be null, then this suggests that a null bean variable might be the cause, which seems a bit odd. I can't tell for sure without delving into the Jasper source code.

This is the tomcat-compiled JSP which is giving the error.

Can I suggest that you use a more recent version of Tomcat?

JIRA ships with 4.1.29, which it is tested & works on - can you upgrade to this version?

I am quite confident that this would be a Tomcat bug.

That did the job - migrating to tomct 4.1.29 fixed the problem.

However, it might be worth noting in the documentation that JIRA does not work 100% on tomcat 4.0.3

Thanks folks.

Thanks for the note. I've added a pointer to this issue from our 4.0 release notes.
