Um, yup. Looks like the IsisSessionTemplate [1] sets up a session, but no
transaction.
The background command service [2] actually subclasses from [1], in
its BackgroundCommandExecution class [3]. If you look through the source
code of that then you'll see how to set up a transaction; basically:
transactionManager.executeWithinTransaction(new
TransactionalClosureAbstract() {
@Override
public void execute() {
...
}
});
Do you think that IsisSessionTemplate should set up a transaction
automatically? I'm thinking it probably should...
