Caleb, Thanks for the quick response. I'll keep digging into it. It's been difficult to reproduce consistently, but it has happened in my dev environment where I am the only user (though I'm not sure if I had the document open in multiple tabs...). It definitely happens more frequently in our production system, though the percentage may be about the same (we have one user who is using that functionality on a regular basis (i.e. that's pretty much all she's been doing for the past several weeks).
I'll go file the issue now. Thanks! --Matt -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Caleb James DeLisle Sent: Friday, September 10, 2010 1:09 PM To: XWiki Users Subject: Re: [xwiki-users] Getting Error number 4001 frequently Hi, It looks as though you have discovered a concurrency bug. What is the version of your installation? If you feel like creating an issue on jira.xwiki.org, that would be great. I will look in to this. A few questions: Does it happen more often when there are a lot of users? Just confirming the page is in /inline/ mode and not /preview/ or /edit/? I ask because The log shows "h.com/xwiki/bin/preview/Project" and the failing template is "/templates/wysiwyginput.vm". Thanks for the report.
