Hi, I'have got a problem with recursive iteration through all subfolders in an External Method. My pc gets out of system-resources doing the following iteration. Does anybody see a problem why this don't stop properly? I have no clue ... -- many thanks for your replies, Elena def sendObject(self, object, objPath): # do something with no effect on iteration return def iterateObjects(self, object, objectPath, basePathLevel, destPath): if object.meta_type == 'Folder': objectPath = destPath + '/' + '/'.join(object.absolute_url().split('/')[basePathLevel-1:]) for child in object.objectValues(): if not (hasattr(child, 'noUpload') and child.noUpload): sendObject(self, child, objectPath) iterateObjects(self, child, objectPath, basePathLevel, destPath) return def uploadObjects(self, ids, destPath, addSubfolder): for objectId in ids: object = getattr(self, objectId) sendObject(self, object, destPath) objectPath = destPath + '/' + objectId if addSubfolder: basePathLevel = len(object.absolute_url().split('/')) iterateObjects(self, object, objectPath, basePathLevel, destPath) return
