I'm trying to pass a XML group content (I'm using XML as datasource) as a parameter to a java method, I need to get this group in java class, format the tags information (name1 + name2 + name3.....nameN) and return it to the JRXML TextField. I can do it for a simple XML tag, but when I try to do it with a group, It appear as null in java method: My XML: <Group1> <Group2> <Person> <Name>John</Name> </Person> <Person> <Name>Mary</Name> </Person> <Person> <Name>Joseph</Name> </Person> </Group2> </Gropup1> My JRXML fields declaration: <field name="group1.group2" class="java.lang.Object"> <fieldDescription><![CDATA[Group1/Group2]]></fieldDescription> </field> <field name="group1.group2.person" class="java.lang.Object"> <fieldDescription><![CDATA[Group1/Group2/Person]]></fieldDescription> </field> <field name="group1.group2.person.name" class="java.lang.String"> <fieldDescription><![CDATA[Group1/Group2/Person/Name]]></fieldDescription> </field> My JRML textField Expression: <textFieldExpression class="java.lang.String"><![CDATA[com.foo.report.MyReport.formatNames($F{group1.group2.person})]]></textFieldExpression> My method signature: public static String formatNames(Object person) {...} Debugging the "formatNames" method, the parameter "person" appear as null. If I change the parameter of textFieldExpression to the field group1.group2 it appear as null too. If I change the parameter of textFieldExpression to the field group1.group2.person.name it appear the String in the java debug: "John". The goal is format the names list to show as: "John - Mary - Joseph" in the textFieldExpression, if someone have another way to do it, please, tell me. Thank you
