Strange Subreport Behavior

2002-10-10 15:52

 

I just noticed the following strange behavior with subreports.

 

I have currently build a master report that takes in a simple data source that iterates through a list of integers.

 

In the <detail> for that report, I do a <printWhenExpression> and test which integer I'm looking for (0, 1, 2... etc)

 

I then have it print a header like 'section details' and include a subreport.

 

 

Everything works fine when the subreport has more than ONE item in it's data source. If there is only a single item in the datasource. then it never shows up in the PDF. I've added println()'s within my JRDataSource object as well, and I do see in fact the next() method is being called properly.

 

Any ideas why it looks fine with 2 items, but never appears with only 1?

Hello,

 

I am generating master report which has two sub reports. When I get more data report come in multiple pages, in such case in each page I am getting both sub reports. But I want the first sub report should be displayed at the first page only, remaining pages should not show first sub report.

 

Any help will be appriciated.

 

Thanks in advance
