使用iReport 5的空白子报表

Question

Why my subreport it isn't shown? Look, the JRXML code is very simple. When I press the view button in iReport only the main report is shown. The two subreports aren't shown. Any help is welcome.

report1_subreport1.jrxml:contains only a static text in the title band

Answer 1

I figure out the problem.

The fields "When no data" were set to "no pages" and should be "All Section, No Detail". Another reason is the second subreport is in deatail band thus won't be printed. I didn't test in runtime, only in iReport however i think it will run.
