Stack Trace when performing category operations

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I have Alfresco Enterprise (trial) 1.3.1 installed (Linux/Tomcat/Oracle DB), and I'm getting all kinds of errors when it comes to categories.  First of all, I go to a document, click the "view details" icon, then go to "run action" in the right panel.  I select the "link item to category" option, then "select values to add".  I click to add a category in the subsequent page, and get a big stack trace.  The below stack trace is what shows up in the tomcat log file, and an abbreviated version shows up on the web client as well.

I have also gotten similar errors when trying to simply add a category directly from the category pane in the document details page, and when trying to add a new category via the admin console.  Help!?!

Hi

From the log messages, it looks like the indexes are not being found - the alf_data directory in the Alfresco installation location.  This only usually happens if you've been moving things around or changing the configuration.  There's a properties file in tomcat/shared/classes/alfresco/extension/ that defines the dir_root location - check what that is set to and whether there is anything at the location defined.

Cheers
Paul.
