Why the elements are moving downwards?

[explorer]

Hi All,

I have created a report that includes sub-report and other elements. All the elements are placed in the summary band.

The report is using JREmptyDataSource as the data source.  The problem I am facing is that the sub-report elements are moving downwards without any obvious reason and are causing mis-alignments.  See the screenshot of the report at http://img818.imageshack.us/img818/3927/reportscreenshot.png

The reports have been created using the iReport designer and the source jrxml files of master and sub-report are attached.

I also had included another sub-report in the master report, but had to delete it as it was not showing at run-time due to the contents of the summary band exceeding the page height. So, what can I do to ensure that the band overflows to the next page when its contents can't be accommodated in a single page?

Thank for any assistance you can offer.
