I played around a little with customizing activity workflows definitions in Alfresco (4.0b).After one of (correct and successful) process definition deployments the "Workflows I've started" list ceased to work displaying "Error loading items" instead. I'm though still able to successfully go through my own (and other) workflows so it also indicates that's not related with my wflow definition itself.Here's the stack trace:13:37:41,804 ERROR [org.springframework.extensions.webscripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: 00200004 Wrapped Exception (with status template): null
