Hello,

I'd like to find out what the problem is in our applicaton currently.

We have a ScrollableResultSet which allows jasper to build reports containing a large quantity of records.

Each group has a subquery for which I want to perform another hibernate query however I have the following problems.

1. in the default way, of say using a pojo seam component with an injected EntityManager, the subquery causes the ScrollableResultSet to close.

The second call to next() on the scrollableresultset raises an exception indicating this.

2. If I wrap the main jasper report process in a seam component with an @Transactional(REQUIRED) method then I cannot access hibernate objects after the initial run.

the second call to next works fine, but the hibernate object within is somehow borked -

   IllegalArgumentException in class: com.me.Location, getter method of property: id

These problems occur at the same point in the process......

Start main report process.....

     load first group

        run first subreport

     load second group <-- !! ERROR !!

How can I run a subquery on the database, whilst another long-running one is active using scroll?

Many thanks for any insights.
