Subject [jira] Commented: (JS2-558) Only "NULL" is shown in browser at what seems to be random intervals.
Date Fri, 19 Jan 2007 07:37:30 GMT

    [ https://issues.apache.org/jira/browse/JS2-558?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12465971
] 

Eivinn Hustveit commented on JS2-558:
-------------------------------------

I think we finally have found out what causes this issue. It is the use of the User-Agent
switcher plug-in in Mozilla Firefox. We are developing services for the mobile phone web-browsers
and "emulate" this software using this plugin. After setting user-agent to some phone and
entering our Jetspeed portal this NULL message comes up. If one switches back to default (UA=Mozilla...)
it all works perfectly.

I assume the best fix would be to support all User-Agents and preferably return a default
site if no mode exist for the given UA.

> Everything works fine in the portal most of the time, but at random intervals "NULL"
is the only text rendered by the browser. I have looked at the jetspeed.log and found out
that it prints out a stacktrace which seems to come from the rendering of the layout portlet.
I will try to upload this as an attachement.
