-----------------------------------

Chris, is this issue still a problem? Could you please attach to this task your project if that is able to reproduce the problem with the current RC1 build. Thank you very much for your bug report and sorry it has taken so long to respond.

>                 URL: https://issues.apache.org/jira/browse/CAY-1092
>             Project: Cayenne
>          Issue Type: Bug
>    Affects Versions: 3.0
>         Environment: PostgreSQL; PostgreSQL JDBC 8.2; using uniqueidentifier as ExtendedType.
>            Reporter: Chris Gamache
>            Assignee: Andrus Adamchik

> Steps to reproduce the problem:
> Create tables, parent and child, with a foreign key link on an ExtendedType
> Create cayenne.xml, and node configurations. Reverse engineer tables.
> Inside your class, create a DataContext, and select a single row from the parent table. 
> Attempt to access the field used as the foreign key.
> ClassCastException is thrown because the wrong return type is used (org.postgresql.util.PGobject instead of java.util.UUID)
> If the cayenne configuration is modified removing the parent-child relation and the project cleaned and recompiled, no ClassCastException is thrown when the parentUuid field is accessed.
> I have an eclipse project that I can provide which demonstrates the problem.
