Grouper Users - Open Discussion List

["GW Brown, Information Systems and Computing" <>]

Hi Steve,

I'm not sure why you are getting the error, but it appears to be occurring 
when the welcome message is rendered - although the message should appear 
at the top of the page this is achieved through CSS and is actually one of 
the last things to be rendered.

The error occurs in /WEB-INF/jsp/subjectView.jsp - which is used widely in 
different contexts:

<c:if test="${viewObject.isGroup}">[</c:if><c:if test="${empty 
inLink}"><span class="<c:out 
value="${viewObject.subjectType}"/>Subject"></c:if><c:out 
value="${viewObject.desc}" /><c:if test="${empty 
inLink}"></span></c:if><c:if test="${viewObject.isGroup}">]</c:if>

viewObject is, in this case, a Map which wraps a Subject instance which 
represents the authenticated user. At a guess viewObject is actually null 
(wouldn't really make sense), or one of the 'methods' is throwing an 
Exception.

Are you using QuickStart users or have you configured your own Subject 
Source - and if so how are they set up?

You could try and pin down the problem by modifying subjectView.jsp e.g. 
replace above with <c:out value="${viewObject.name}"/> - or change 'name' 
for an attribute you know to be present. If this works, you can change the 
attribute for: isGroup, subjectType and desc and see if it fails on one of 
those - desc would map to description.

Regards,

Gary
