Uses script code from the Apache-BeanScriptingFramework to calculate values within a single row of a report. |
Note: Release 0.8.9-ga is not working with JavaScript due to a Jar-Version conflict. To resolve it, upgrade to BSF-2.4.0 and Rhino-1.6r7.
The expression will use the last statement as return value. This statement must either be an dummy assignment statement or a method/function call that returns a value.
