1.1-rc1 Struts-EL 'errors' tag causes NPE
Summary: 1.1-rc1 Struts-EL 'errors' tag causes NPE
Product: Struts
Version: Unknown
Platform: PC
OS/Version: Windows NT/2K
Status: NEW
Severity: Normal
Priority: Other
Component: Unknown
AssignedTo: struts-dev@jakarta.apache.org
ReportedBy: wendywds@hotmail.com
(1.1 RC1 is not listed in the 'Version' select list, and I'm not sure
what 'Component' to choose for Struts-EL)
The <html-el:errors/> tag causes a NullPointerException on any page it's used
in.
This page:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html-el.tld" prefix="html-el" %>
<html>
<body>
<html-el:errors />
</body>
</html>
when saved as 'test.jsp' in the root directory of the strutsel-exercise-taglib
webapp that ships with 1.1-rc1 in the 'contrib' directory and accessed with a
browser, produces this error:
HTTP Status 500 -
