Hi there again,

I'm getting an error out of my code, and I don't really understand why I'm getting it, or what to do about it!

I'm using Class::DBI::Relationship::IsA to allow myself to subclass Users of my system. The Users package is as follows:
#!/usr/bin/perl

package MyDB::Users;
use base 'MyDB::DBI';
MyDB::Users->table('USERS');
MyDB::Users->columns(
    All => qw/USERNAME PASS USERTYPE EMAIL/);
MyDB::Users->might_have(
    CANDIDATE => 'MyDB::Candidates' => qw/FIRSTNAME LASTNAME DISABLED 
+CV/);
MyDB::Users->might_have(
    CLIENT => 'MyDB::Clients' => qw/NAME MAXROLES MAXCOMPETENCIES/);
1;

A User can be either a Client or a Candidate: 
#!/usr/bin/perl

package MyDB::Candidates;
use base 'MyDB::DBI';
use MyDB::Users;
MyDB::Candidates->table('CANDIDATES');
MyDB::Candidates->columns( All =>
qw/USERNAME FIRSTNAME LASTNAME DISABLED/
);

MyDB::Candidates->is_a( USERNAME => 'MyDB::Users' );
1;

and 
#!/usr/bin/perl

package MyDB::Clients;
use base 'MyDB::DBI';
use MyDB::Users;
MyDB::Clients->table('CLIENTS');
MyDB::Clients->columns(
All => qw/USERNAME NAME MAXROLES MAXCOMPETENCIES/);
MyDB::Clients->is_a( USERNAME => 'MyDB::Users');
1;

Anyway... The problem comes when in the code for the app itself I call 
my @objs = MyDB::Clients->retrieve_all();

At which point I get the error:

Can't locate object method "username" via package "ctmclient" (perhaps you forgot to load "ctmclient"?) at Class/DBI/Relationship/IsA.pm line 311.

(ctmclient is the username of the one client which I have inserted into the database - it is in the Clients and Users tables correctly). Anyway, can anyone point me towards where I might be going wrong. The docs for IsA seem to be a bit sketchy at best.

Thanks in advance.

Mel
