I have .jrxml with generating the PDF and everthing works fine. But sometimes i need to add dynamically another item of table's items. How to do that? I'm new in this field and only once to create this pdf. Also attached the format of output. I have this json: { "customerName": "derr", "customerEmail": "sss.dd@gmail.com", "invoiceNumber": "1", "invoiceAmount": "180", "invoiceDate": "2021-08-30", "poNumber": "234234", "productName": "Hilton Milano", "price": "180", "vat": "0", "lineTotal": "180", "currency": "EUR"}[/code]And i think to change to new format: { "customerName": "derr", "customerEmail": "sss.dd@gmail.com", "items": [ { "invoiceNumber": "1", "invoiceAmount": "180", "invoiceDate": "2021-08-30", "poNumber": "234234", "productName": "Hilton Milano", "price": "180", "vat": "0", "lineTotal": "180", "currency": "EUR" }, { "invoiceNumber": "2", "invoiceAmount": "180", "invoiceDate": "2021-08-30", "poNumber": "45455", "productName": "Item2", "price": "180", "vat": "0", "lineTotal": "180", "currency": "EUR" }
