问题 I need to make a grand total of the items I'm counting in a subReport. To do that, I think I need to add the value of that variable to another variable for each iteration, or "increment" it by that value. The subReport gets called for each group, and I get a total for that group. I need to add the variable values, rather than database columns/fields. I'm receiving an integer returnValue from the subReport , which is itself the count of rows in the sub-report. I want to get the grand total,

问题 I have sub Dataset that include a calculated variable that I want to show in the report. But when dragging and dropping this variable into the report the following message appears: You drop an object from a subdataset to the report, this is not possible.

问题 I have a clean Jasper report that calls a subreport with no filter. In that subreport I show all the Json data (10 rows), and if I see the preview it works: Subreport preview. The problem is when I call the subreport from the main (and clean) report. It only has in the detail the professionalName and the subreport. It should show the professionalName and all the subReport (all 10 rows each time), but it's not the case. It only shows the current row, and I'm sure it's because the main report

问题 frame text field: short | text field: very long text causing linebreak frame other elements How do I have to configure jasper reports so that the long text field moves all subsequent frames and elements down? (ie: causes a resize of the frames dynamically)? 回答1: Solution: make the text fields float; stretch relative to tallest object; overflow and make the surrounding frames float; no stretch . This is very counter-intuitive that an expanding frame will have to be set to no stretch in order
