Multiple subreports: jasper is not correct?

2003-04-16 01:47

Hi:

 

I am using a lot of subreports (13).

When fill process starts it creates 13 threads (one for each subreport).

That's ok.

 

BUT my problem is the page height: if subreport's band does not fit on the

remaining space on the current page its thread waits, and the next thread

fills that remaining space with its data. And when jasper adds a new page,

the thread that was waiting is notified and begins to fill in this new page.

 

Conclusion:

Report is not presented with the information in the right order.

 

Example:

Subreport A (5 records)

Subreport B (3 records)

Subreport C (1 record)

Subreport D (3 records)

...

 

A posible result can be:

 

Begin report

A1

A2

A3

B1

B2

A4

A5

B3

D1

C1

D2

D3

End report

 

 

 

Where is controlled the remaining space in the source code?

 

Thanks a lot!

I know that problem too.

 

But you can try the following:

Don't use the detail-band, instead place each subreport in a dummy-group with group-expression $V{REPORT_COUNT}.

Finally it worked.

 

I tried dummy-groups before and didn't work. But as you said, I tried again and it works!

 

Thank you, Heinz.
