My task [Error loading items]

doucouredave

Hello All

I encounter an error in My Alfresco tasks list page and taks list dashlet.
I am using alfresco community 4.0.d Mysql 5.5 on MS server 2008.

Description:
When a user goes to the page "My Taks", he gets the error "Error loading items".
Similarly, the dashlet "My Task" shows all the time "Loading …".

My log:

Trying to debug, I see that via firebug, the ajax callback (link bellow) returns an error 500.

I encounter this issue on a recently upgraded instance (3.4.d to 4.0.d).

Help is very appreciated.

thanks

Hello,

hmm, this problem can only occur if

a) you have a loop in your group memberships, which should not occur "naturally" due to checks performed by Alfresco
b) you have an unnaturally deep group structure and very small stack memory size (very unlikely, since you would need a freakishly small stack size or freakishly deep group structure)

Please check assumption a) via the node browser.

Regards
Axel
