Hi all,
I am continuing from [1].
I have now problems with a range-enabled JPQL query.
The problematic code is in DistributedStoreQuery, around lines 149:167,
triggered by Syncope's JPATaskDAO [2].
From there an instance of RangeResultObjectProvider wrapping
OrderingMergedResultObjectProvider, wrapping in turn
InstanceResultObjectProvider is returned.
Then, RangeResultObjectProvider#next() is invoked, and this works fine
when the required range is (0, 2): when, instead the range is (2, 4), I
see that _delegate.next() is called (line 91 from
RangeResultObjectProvider) and this "consumes" the underlying result
set, thus resulting in an empty query result.
Does anyone see any obvious problem here?
TIA
Regards.
