	Hi,
I agree, both seems fine, at least from the description (the actual code
can be slightly different, especially with the opening phase). The
start_view part is pretty much the same as for example for CalDAV
backend.

I suppose the get_view_cb comes from e-cal-model.c in evolution, right?
Could you set a break point there, in gdb, and check what failed there
(error->message), because it seems there is failing something. You can
also run evolution from console, whether it'll claim anything there.

The easiest way to check out this would be to share your code, the one
involving opening phase (implementation of ECalBackend::open,
ECalBackend::authenticate_user and ECalBackend::start_view). By the way,
is you backend's parent class ECalBackend or ECalBackendSync?
