问题
The summary band is always aligned to the bottom of the page when there is only 1 page. But when the summary band doesn't fit on the first page, it will be shown on the second page. If there is no Detail on the second page, only the summary band will be shown (together with the header and footer bands).
Is it possible to align the Summary band to the bottom of the page, just like the footer?
This would help me a lot in my current layout design.
