Hello! I'm migrating some reports from JasperReports 2.0.2 to 3.7.4. Some of them create and define group header and footer programmatically. Example: JRDesignGroup myGroup = new JRDesignGroup(); JRDesignBand myGroupHeader = new JRDesignBand(); ... JRDesignBand myGroupFooter = new JRDesignBand(); ... myGroup.setGroupHeader(myGroupHeader); myGroup.setGroupFooter(myGroupFooter); The methods setGroupHeader and setGroupFooter are deprecated. Javadoc only says that they were replaced by JRBaseGroup.getGroupHeaderSection() and JRBaseGroup.getGroupFooterSection(). I'm not seeing how I can set a group header/footer after calling getGroupHeaderSection/getGroupFooterSection. Someone has an example?
