The issue is, fpreport handle the Databand not correct.
All have no Masterband set
A ) If i bound no Data to a Databand, automatic the dataset of the
parent (Page) is used -> Ok yet -> Dataloop of parent is used
B ) If i bound Data to a Databand and it is the same like the parent
(page) -> Ok -> Dataloop of parent is used
C ) If i bound Data to a Databand and it is not the same like the parent
-> Not Ok -> the first it is handled like B - it should use their own
You can make this with a fake working. Make a dummy Databand with a
Dataset with ONE entry only. Then bound the datasets as childdatasets
and it works.
You see the problem with the FPReport Designer too.
- Make a new report
- add two datasets (eg, csv with valid data)
- add PageheaderBand, TitleBand and PageFooterband
- add a Databand bound the Data1 to it
- add a Databand bound the Data2 to it
Make a Report Preview -> only the contend of the first dataset is shown.
I will file a bug
