Indigo on Windows 7 Pro 64bit
Just bringing up an app for the first time; my datastore code is a close copy of various examples out there, and is just trying to save a single simple object.
The pm.MakePersistent(o) apparently succeeds (i.e. doesn't throw an exception), but the datastore viewer shows no objects, and the local_db.bin file does not appear (although datastore-indexes-auto.xml was generated in that directory).
A subsequent query for the object (using a known field value) returns nothing (unsurprising given the viewer shows nothing.)
I suspect a workspace configuration problem, but would have thought some sort of error would have appeared...
