I call rsv_info.getField("info_type") because I need to use the value
returned. It's not for display purposes.
Since I call rsv_info.getField("info_type") in the <db:body> tag I thought
dbform should not execute the <db:body> tag if there are no records returned
(and hence resultsetVector is null) or if it must execute <db:body> for some
reasons then I expect to get a null value when I call
rsv_info.getField("info_type") instead of an exception.
