[xwiki-users] Bug : Some statistics are displayed but not all are recorded and some crash - xwiki-users@xwiki.org

6 Mar 2009

Hello,

The statistics are activated in the xwiki.cfg file. When i go in the Stats space (in a
virtual wiki) or not i have some data like "Most viewes pages", "Most
active contributors" but some got me a Velocity parsing error and generates an
uncatchs java exception in JodaTimePluginApi :

Error number 4001 in 4: Error while parsing velocity page Stats.WebHome
Wrapped Exception: Failed to evaluate content with id Web Home
com.xpn.xwiki.XWikiException: Error number 4001 in 4: Error while parsing velocity page
Stats.WebHome

Is there any patch for that ?

Also if i go on the activity statistics page i have 4 times the same error (i guess one
time per graphic)
