First thing I notice from the commands is that you did not register the
view in geometry_columns. How can the datastore know about the SRS
and geometry columns of the view if you don't?
Yet, a NPE is a very bad reaction, the situation must dealt with it more
gracefully. I'll have a look into it.
Oh... where did the OID issue end up?
