6.7. Fields

A report can declare a number of fields. Fields represent named objects that are obtained from the data source at the moment of report execution. A field declaration provides all the necessary information required by the report engine to extract the value. Once declared, they can be referred to in expressions using a dedicated syntax. JasperAssistant groups these declarations under a single Fields node in the Outline View. New fields can be added by using the context menu associated to this node.
