Re: [xwiki-users] MIT Simile Widgets (spiffy JS Timeline/Timeplot/Timegrid) for Xwiki?

Hi Niels, Thank you for your insight. I am almost sure that doc names and spaces have not inappropriate characters, but I can not be so sure about titles. My first trial following your message has been to test your code in a XWIKI ENTERPRISE 1.7-MILESTONE-3.14362 It worked without a glitch. Of course this not solve the doubt if the reason for the failure is in the contents. I think that is time to face the update process with this server and eliminate some possible causes. I need to reach the end of February with this installation untouched. I will be move then to XE 1.7.3.

I will be back ASAP!
