Hi, I get exactly the same error after installing the AdaptableStorage-Product with two mount_paths connected and accessing the the folder-object with the second-one. See an earlier posting to this list. -- Elena My earlier posting with error: Hi Shane, in my ZMI there are two folders: pathA and pathB and I use your AdaptableStorageProduct for FileSystemStorage with the two mount_paths=/pathA/zptTexte; /pathB/zptTexte so that the zptTexte get mounted to these Folders in the ZMI. It works initially but when I try to copy anything in the pathA-Folder in the ZMI , I get a RuntimeError. Same happens as soon as I try to enter the folder pathA in the ZMI afterwards. Is there any solution for that? Or can use only one mount_path? -- many thanks for your replies, Elena Error Type: RuntimeError Error Value: Shouldn't load state for '(\x01\x00\x00\x00s\x18\x00\x00\x00/project_health/zptTexte' when the connection is closed Error error_tb: Traceback (innermost last): Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 252, in __call__ Module Shared.DC.Scripts.Bindings, line 283, in _bindAndExec Module App.special_dtml, line 174, in _exec Module DocumentTemplate.DT_In, line 705, in renderwob Module Products.AdaptableStorage.zodb.ASConnection, line 302, in setstate RuntimeError: Shouldn't load state for '(\x01\x00\x00\x00s\x18\x00\x00\x00/project_health/zptTexte' when the connection is closed
