hello jessica,
you are right - more details would be great!
e.g.:
does the wrong behaviour change without ppr?
(just to avoid that there is a "general" problem... - please change your
page to answer this question - it's just for this test...)
which scope did you choose for the dataReportsLoader-bean?
regards,
gerhard
