Backgroud:
Use Java + BIRT to generate report.
Generate report in viewer and allow user to choose to export it to different format (pdf, xls, word...).
All program are in "Layout", no program in "Master Page".
Have 1 "Data Set". The fields in "Layout" refer to this DS.
There is Group in "Layout", gropu by one field.
In "Group Header", I create one cell to use as page number. "Page : MyPageNumber".
"MyPageNumber" is a field I define which would +1 in Group Header.
Problem:
When I use 1st method to generate report, "MyPageNumber" could not show correctly. Because group header only load one time for each group. It would always show 1.
Question:
As I know there is "restart page number in group" in Crystal report. How to restart page in BIRT?
I want to show data of different group in 1 report file, and the page number start from 1 for each group.
