I have deployed jforum portlet and added it on content page of jahia 5.0
and it was working very fine but today I found very weird error. I did
not do any modifications in it, suddenly I got error. Can someone
explain the possible cause of the error? Is jForum has some inbuilt bug
in it?
Jforum is developped with freemarker
(http://freemarker.sourceforge.net/). If there is a bug you may have
this kind of message:
Expression templateName is undefined on ...
If you've done nothing, maybe the database connection was broken due
to database connection timeout.
See http://www.jforum.net/ for more details about jforum.
KT.
Expression templateName is undefined on line 5, column 14 in
exception.html. The problematic instruction: ---------- ==>
${templateName} [on line 5, column 12 in exception.html] in include
"${templateName}/message.htm" [on line 5, column 1 in exception.html]
---------- Java backtrace for programmers: ----------
