Several crosstab reports

[stopbugginme]

 Hello.

I need to make a very complex report,  which I don't know, at design time, how many data (columns and rows) the report will have to show. I've found that crosstabs would fit my problem, but I'm facing a lot of difficulties.

I need the report to show each table in a different page. I've tried to have lots of detail bands, each one with a subreport with a crosstab in it, separated by page break elements; and I've tried to have a lot of crosstabs, in the same report summary, each one separated by page break elements too.

None o those solutions worked fine: in the first one, the report doesn't show all the data in the crosstab, actually it shows only the first subreport (and, yes, I've configured the datasource for each subreport); in the second solution, configuring different subdatasets for each crosstab does not work at all, but when I use the same datasource it seems to work fine.

I'm using a simple JRBeanCollectionDataSource to fill the report data, and today, when I added more than two objects into the collection (!), I received the following exception:

java.lang.ArrayIndexOutOfBoundsException: 1

I'm desperate. Really. I'm trying to make this report for a week now, and really don't know what to do anymore. Has anybody a suggest to solve my problem or something?
