I'm trying to accomplish some requirements with a report I'm designing for a desktop app. I'll try to explain myself as clearly as it's possible to me. The situation is as follows:
I have a report with a simple table in the <detail>
band and then a very big section of some static text and 2 or 3 expressions, which should correspond to the <summary>
band. In a first moment, I tried to put all that information in the <summary>
but then I found out the 656px height limitation for JasperReports bands.
My second attempt to solve that problem was to put that static summary information in a subreport. That way I was able to use <title>
and <summary>
bands to put the fields in both bands and don't have to worry about band height limitation. The problem with that solution is that I wasn't able to show page numbers (from the first report) in the subreport section (which has 2 or 3 pages). I found the option of page footer and header in summary (a checkbox in Jaspersoft Studio which is isSummaryWithPageHeaderAndFooter="true"
property in <jasperReport>
element) but then my report gave me a compilation error on preview; don't know if it's a bug in Jaspersoft Studio: I tried in the 2 latest versions and the error was the same.
Finally, I tried to add a second <detail>
band with a different query which returns only a single value. The problem now is that I wasn't able to put the second detail band "below" the first: in the preview I see one row from each band alternately, and not as I need. After searching a lot I found out that this is not possible.
Summary requirements causing problems
The summary has the following requirements:
- Has severals static text fields and some other expressions with calculated fields and parameters (formatted dates and things like that).
- Those pages must be paginated (page [current] of [total] in the footer).
- The datasource and the query is the same for the main report and the summary.
The first requirement makes the summary band to need a height bigger than 656px, which is the max allowed for that band. So I tried the solutions described briefly above. I'll describe now the problems for the subreport approach.
Subreport with isSummaryWithPageHeaderAndFooter="true"
When I try to preview the report from Jaspersoft Studio with this approach, first I get the following state (before the IDE ask for the parameter):
When I enter the parameter, I get the following state:
and after that the times and the pages keep growing until the program crashes. The same behavior happens in different installations: I tried versions 6.3.1 and 6.4.0 in both Windows 7 and Mac OS. HOWEVER, compiling the report from the IDE is successful (I mean it generates the .jasper
file) with the compile report option.
But when I export the report to PDF (or display it with JasperViewer
) it doesn't render with page footer in summary band.
Note: Compiling the report from a simple Java app doesn't gives me any error.
Any help is welcomed. Thanks in advance.
