I have created a two level folder structure. A folder on the second level has a rule that sets the file type, and an aspect that creates some smart folders and adds/sets some properties on files when they are moved into the folder (very similar to the claims example in the smart folders tutorial - see https://docs.alfresco.com/community/tasks/sf-tutorial.html). When a file is dragged into one of the smart folders, the file is typed, aspects added, and properties populated successfully.
However, I am subsequently unable to move those files into other folders, to either the root (Documents) or second level. Alfresco logs show
"2018-05-17 14:49:33,120 ERROR [org.alfresco.repo.virtual.store.TypeVirtualizationMethod] [http-apr-8080-exec-45] Type virtualization template search failed.
org.alfresco.traitextender.ExtensionTargetException: java.lang.StackOverflowError" and a long trace.
