Expression request.getParameter is undefined on line 97, column 94 in default/post_show.htm.

When creating a poll and looking at it logged in as a user that did not vote yet, I'm getting the following error:

15:54:34,795 ERROR [runtime ]

URL is: /forum/posts/list/17.page?null

The offending line in post_show.html is:

<#if (poll.open && canVoteOnPoll && !request.getParameter("viewResults")?exists)>

Problem can be seen on:

http://play.onlinefrontlines.com/forum/posts/list/17.page

(you need to LOGIN and register first for it to occur)

Any ideas?

I'm using SSO

Freemarker errors like this tend to be the result of some underlying problem that is not reported to the browser. Check your application server log files to see if there are any associated errors there.

Hello,

The text you're seeing above comes from the tomcat log folder. I don't see any other text in the log that could relate to this problem.

Jorrit.
