> Key: FORGE-911
> URL: https://issues.jboss.org/browse/FORGE-911
> Project: Forge
> Issue Type: Story
> Components: Scaffold
> Affects Versions: 1.2.3.Final, 1.3.0.Final
> Environment: Linux 3.8 - Firefox - MySQL 5.5 - PostgreSQl 9.1
> Reporter: Hanine Hanynowsky
>
> Using JForge (latest version); one will have a hibernate error complaining about the M2M join table (linking two objects) having more than 2 key columns.
> Naturally, if you join a table with one key column with a another table with a composite primary key (two columns key), in order to get a Many to Many relationship, you'll end up with a join table that has three key columns.
>
> When Forge finished scaffolding no error is displayed. You get the error when deploying to the container (JBoss as 7.1.1 for example). And the app is not deployed (rolled back).
>
> Is this a bug? A feature request?
>
> It seems to me that with the EmbeddedId bug, this one is also serious stuff!!
