Lists, Tables, and BarcodesFigure 14-22 Deleting a column groupThis message informs the user that the column we are being to move is the only column inside a column group which will beremoves after the column has moved, since the group will not contain at that point any other columns.Alternatively, columns can be moved using the Report Inspector by dragging the nodes that represent columns, in the newlocation within the same section.To remove a column, select a cell of the column (or the column node in the inspector view) and select Delete column from thecontextual menu item.14.2.6 CompatibilityIf a previous version of UR is used, an error will be reported. Since the error usually refers to the JRXML syntax,it can appear really cryptic. Here is a message you may get:org.xml.sax.SAXParseException: cvc-complex-type.2.4.a: Invalid content was found startingwith element 'jr:table'. One of '{"http://jasperreports.sourceforge.net/jasperreports":component}' is expected.The error is just saying that the component table in the namespace jr is not known and cannot be understood or used. Thesolution is to remove the Table element or upgrade.14.3 BarcodesThe barcodes are rendered by two open source libraries: Barbecue and Barcode4J. When a new Barcode element is added to areport, the user can choose which library to use. Both libraries provide a variety of barcode types, but there are differences inthe options that can be set. We will see them later. The choice of which library to use may be influenced by other factors, aswell; for instance, if a particular library is already used in an application, the designer can choose to use the same library todesign the reports, as well.293
