Kevin Meyer commented on ISIS-118:
----------------------------------
Some collection support has been added.
Superclass properties might even be detected, too.
> Persist and restore polymorphic classes

> Key: ISIS-118
> URL: https://issues.apache.org/jira/browse/ISIS-118
> Project: Isis
> Issue Type: Bug
> Components: Runtimes: Dflt: Objectstores: SQL
> Affects Versions: 0.1.2-incubating
> Reporter: Kevin Meyer
> Assignee: Kevin Meyer
>
> Currently, the SQL OS does not persist properties of super-classes when a
> polymorphic class is persisted. Additionally, abstract classes and interfaces
> are treated the same as concrete classes.
> There are two obvious options:
> 1) The persisted polymorphic class creates a row in an uber-table of
> concatenated properties of all super-classes.
> 2) The persisted polymorphic class creates rows in each table that
> corresponds to a super-class (the concrete sub-class is contained in multiple
> tables, 1 per super-class).
