Reorder pages causes nullpointer exception

[Deleted user]

When we want to re-order the pages of one of our large spaces, the page never loads and the "thinking circle" is shown forever... The link we're accessing is:

https://confluence.xyz.com/pages/reorderpages.action?key=MD

And the stack trace from the logs:

2013-08-26 14:06:08,499 WARN [http-8080-16] [opensymphony.xwork.util.OgnlValueStack] findValue Caught an exception while evaluating expression 'JSONString' against value stack

(it's actually a lot longer but I think this is the important part)

I found this, which isn't exactly the same, tried the resolution but the select does not generate any rows.

Anyone got any ideas? We're running Confluence 5.1.3.

Hi Marcus,

From the stacktrace, you might be hitting the following issues.

Please try the resolution out and check if it works.
