Based on what I have found on the Web, I have this in my Properties: === er.extensions.ERXEC.safeLocking=true er.extensions.ERXEC.useSharedEditingContext=false er.extensions.ERXApplication.useEditingContextUnlocker=true er.extensions.ERXEC.defaultAutomaticLockUnlock=true er.extensions.ERXEC.defaultCoalesceAutoLocks=true === > > (Besides frankly, I don't really see the need to lock an EC at all, given the > EC is created, used and released in one separate thread and never shared > anyhow with other threads; but then, superfluous locking does not harm > anything but efficiency, and efficiency is not paramount with background > threads.) > > You not seeing the need, does not mean the need is not there. :-) EOF sends > out a lot of notifications, an unlocked EC will process those notifications > immediately and that can mutate the EO state (attributes, relationships). > You won’t have a consistent view of the world in an unlocked EC.

Have fun with that! > :-) Anyway, just to be triple sure, I have changed my task code to === class ImportCSVTask extends ERXLongResponseTask.DefaultImplementation { ... def editingContext ... def performAction { ... try { editingContext=ERXEC.newEditingContext(objectStore=new EOObjectStoreCoordinator()) editingContext.lock() ... all the processing here, actually imports CSV, stores objects to editingContext and saves it ... } finally { editingContext.unlock() } } } === I hope there's no problem with that?
