I think your issue relates to a misunderstanding about the "property"
attribute. I see that you have added "ReportParameters" at the front
of all your property references. My guess is that you don't need
that. iBATIS would expect "ReportParameters" to be a property of your
parameter object - and I'm guessing that "ReportParameters" IS your
parameter object. So, remove "ReportParameters" and things will
likely improve.
