Wondering if anyone has come across this particular problem. We are testing Zope 2.7.2 with Ape 1.0 set up to use the file system mapping and is mounted at the root. ie %import Products.Ape <ape-db main> <ape-storage> mapper-variation filesystem <ape-fs-connection fs> basepath $INSTANCE/var/fs </ape-fs-connection> </ape-storage> mount-point / scan-interval 1 </ape-db> Most things work fine, but when we go to a product in the Products folder and click on the Refresh tab, we get:: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module App.Product, line 341, in manage_refresh Module App.RefreshFuncs, line 57, in isAutoRefreshEnabled Module App.RefreshFuncs, line 47, in _getCentralRefreshData AttributeError: UnmanagedJar instance has no attribute 'root' Also, in the same area, if we click on the undo tab, we get:: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module Shared.DC.Scripts.Bindings, line 306, in __call__ Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec Module App.special_dtml, line 175, in _exec Module App.Undo, line 100, in undoable_transactions AttributeError: UnmanagedJar instance has no attribute 'db' And finally, we were testing ZClasses (adding them), we get: Traceback (innermost last): Module ZPublisher.Publish, line 101, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module ZClasses.ZClass, line 150, in manage_addZClass Module OFS.ObjectManager, line 276, in _setObject Module ZClasses.ZClass, line 422, in manage_afterAdd Module ZClasses.ZClass, line 374, in _register AttributeError: UnmanagedJar instance has no attribute 'root' Google does not find anything and a cursory look at the class definition of UnmanagedJar in connection.py doesn't reveal anything obvious. Has anyone else run into a similiar problem or have any suggestions. Thanks for your time, -Chris
