Enable new TrashService

API Changes The new TrashService fires dedicated events documentTrashed and documentUntrashed (hold by TrashService interface) instead of lifecycle_transition_event . The document model passed in the event won't be saved by Nuxeo at the end. Keeping Old Trash implementation The trash implementation has changed in 10.2. If you want to keep previous implementation relying on life cycle state, add the following contribution: <require>org.nuxeo.ecm.core.trash.service.migrator</require> <extension target= "org.nuxeo.runtime.migration.MigrationService" point= "configuration" > <migration id= "trash-storage" > <defaultState>lifecycle</defaultState> </migration> </extension> If you want to migrate trash state to the new property model (ecm:isTrashed), follow the Trash migrations steps. Trash Migration To migrate trash states to the new property model: Follow the step from section Keeping old trash implementation. In the Nuxeo Platform's JSF UI, go to Admin > System Information > Migration, click the button Migrate trashed state from lifecycle to property and wait until migration is completed. Remove the contribution added at step 1. INFO: during migration, document in state deleted will receive the isTrashed property set to true but migrator will leave document in deleted state
