Jivan Phadtare Posted June 2, 2023 Share Posted June 2, 2023 Hello,Per error trace, it looks like isSplitTypePreventInhibited is called on null. Seems to happen when a table is located in a detail band and the cell of the table is overflowing, that is generating a page break.Found similar error on below community portal.https://community.jaspersoft.com/jasperreports-library/issues/10451Hope this finds you useful !!
