[Seaside] Slightly OT -- Glorp session question..

[Boris Popov]

Typically instead of a single descriptor you create descriptor systems that
describe your whole domain by subclassing DescriptorSystem and then creating
your session via,

system := MyDescriptorSystem forPlatform: login database.
session := GlorpSession new.
session accessor: (DatabaseAccessor forLogin: login).
session system: system. 

There should be plenty of examples in GlorpTest for this.

Hope this helps,

-Boris

Below is how my db connection is setup :
          [ login code is skipped for this ]
            db := Glorp.GlorpSession new.
            db system: (MSADBUserDescriptor forPlatform: login database).
            db accessor: accessor

Once I do that I can issue the following and get an array of users:
    users := db readManyOf: MSADBUser.

However, if I want to read one of the other tables using something like 
the following:
    states := db readManyOf: MSADBLocationLookup.

I get an exception "Message not understood: 
#classesRequiringIndependentQueries"

So, I'm guessing I need to use some other Glorp mechanism or change my 
"db system: ..." line
from above to add more descriptors for other tables I might be reading 
during the same Seaside
session or same Glorp session.. Am I barking up the right tree here?

TIA!
