JasperReports: nested records do not work with positionType = 'Float'

Question

In this example, the overlap overlaps - what am I doing wrong? The second should “float” below the first, while its “y” attribute is ignored, but it is not.

Thanks!

Answer 1

I got an answer! (I am the one who asked, in another IP) According to the documentation, a floating element will ignore its y-attribute. I took it literally, tried arbitrary values ​​for y and saw that every time an element was placed at the specified position.

But no, you need to set y to position the element directly below the previous one, in accordance with the specified y element and height , although its actual height can be stretched when filling with data. In my code example, the second subreport should have y = "50".

In addition, I see that the declared height of the element is taken as the minimum height. If the actual sub-register is shorter than the height, the closing element will not shrink, so it would be nice to set the minimum expected height for elements that could stretch.

You are right, but you need more. You need to remove fields from subscriptions.

• From the menu → Format → Delete report fields from the menu

• Format → Page Format → Make Fields 0
