Hello Rohit,
The line number might be off in my view; it shows that the row
might be
null and I am not sure what could cause that without an
exception or
problem occuring in the query.
Can you send the log just showing the query and the exception
with
logging set to finest? Does it go through any iterations
before the
exception occurs, or is it the fist call to hasNext that
throws the
exception?
Can you also check the results from executing the generated
SQL
manually?
Best Regards,
Chris

Hi All
I am getting a NullPointerException
when trying to
execute a ReadAllQuery with scrollable cursor enabled. It
seems that
the exception happens when it tries to access the many side
of the
mapping.
I am using Eclipselink-2.3. Here is the stack trace:
Exception in thread "main"
java.lang.NullPointerException

I have attached the sample code along with this mail. Can
someone
please have a look at it and see what is amiss?
Thanks in Advance!
