How to bind footnotes in JasperReports

Question

I have Textfields with dynamic position. It has footnotes, e.g. "some text¹". And this footnotes are in the footer.

Footenote must be on the same page with textfield. Textfield has a float position and its location depends from dynamic size of Textfields above. With different conditions the field is located on different pages

How to bind TextField whith footnote in one page, e.g. Textfield is on the page number 3 and footnote on the same page? I can use $V{PAGE_NUMBER}, but how to get current page of TextField?

Answer 1

I have added $P{REPORT_PARAMETERS_MAP}.put("id_1",$V{PAGE_NUMBER})) at the end of textFiled Expression and $V{PAGE_NUMBER}.equals($P{REPORT_PARAMETERS_MAP}.get("id_1")) in the PrintWhenExpression of textField in the footer
