I forgot to mention, I am using JasperSoft Studio 5.5.1, and Jasper Reports library version 5.5.1.

Using PositionType=Float seems to cause the report to take a really long time to generate, and during that time the thread generating it dies with an OutOfMemoryError. I have just tried using extra detail bands like you said, but now each detail band appears on a separate page. I then tried setting "Ignore Pagination" on the report to true, but now it won't start a new page on a new report record, and instead only starts a new page when the data is too long for the same page. I definitely need all the detail bands on the one page (except when the data is too long of course), and to have each report record appear on a new page. Also, I still have the problem that some of the static text labels are missing.

I have made the changes you suggested, though I attached a PDF sample report instead of making screenshots.

I am using Jaspersoft Stuido. I have a master report that contains three sub-reports, named "vehicleListSubReport.jrxml", "locoSubreport.jrxml", and "crewSubreport.jrxml" Their datasources are the fields "vehicleReport", "locoReport" and "crewReport" respectively, which are all objects of type JRDataSource. I have attached the jrxml file for the master report, and a pdf file for a sample of the output. I am having a few problems, but I feel that they may have a single root cause, hence why I am asking about them all in the same question. First problem: The crewSubreport has other report elements below it, including the other two sub-reports. If there are multiple records in this sub-report, it renders on top of the elements below it, including the other sub-reports. Second problem: The data text fields below the crewSubreport are rendering (although with the subreport rendering on top of them), however, the static text boxes with the labels "Train Summary", "Number Vehicles:", "Tonnes Hauled:", "Total Length:", "Locos:", and "Tonnes Gross:" are not rendering, and I not yet able to determine why. Third problem: Similar to the first problem, the locoSubreport is rendering into the space occupied by the vehicleListSubreport. How do I fix these issues? EDIT: I am adding the jrxml file that I made by changing the position type of the elements below the first subreport to "Float". I am hoping someone can explain why this approach causes my program to throw the following OutOfMemoryError:
