>             Project: Apache MetaModel
>          Issue Type: Bug
>    Affects Versions: 4.4.1
>            Reporter: Geraud Campion
>            Priority: Minor

> Many of the other DataContext's Datasets allow you to iterate through the dataset multiple times. However, JDBCDataContext only allows you to do this once.  To workaround, I can reexecute the query before iterating the second time.
> I believe this is caused by executing statements using ResultSet.TYPE_FORWARD_ONLY. This may not actually be a bug. I am not sure if this is by design to provide better performance and ensure concurrency.
