More than one root node? 0

[federico]

Hi all,
I've deployed the alfresco.war (v. 1.0.0) on a 5.0.24 tomcat hosted on a linux box.
I've a problem while a try to manage categories.
All the operations that involve categories (view, creation) fail with this message:
A system error happened during the operation: More than one root node? 0

Could you give me some hints in order to fix the problem?

Thanks
Federico

Hi Federico,

This is normally caused by your indexes being out of sync with the database, have a look at this article: http://www.alfresco.org/forums/viewtopic.php?t=365&highlight=.

Also I notice you are using Tomcat 5.0.24. Alfresco requires Java 1.5 and I believe there are some issues with Tomcat 5.0.x and Java 1.5. If you get any errors regarding classes i.e. classloading, class format versions etc. try upgrading to Tomcat 5.5.x.

Hope that helps,
