>                 URL: https://issues.apache.org/jira/browse/WW-3266
>             Project: Struts 2
>          Issue Type: Improvement
>          Components: Plugin - JasperReports
>    Affects Versions: 2.1.6
>         Environment: JasperReports 3.6
> Groovy 1.5.5
> JDK 1.6 (MAC JDK) 
>            Reporter: Matt Jiang

> Current implementation:
> String expression = field.getDescription();
> if (expression == null) {
>     //Description is optional so use the field name as a default
>     expression = field.getName();
> }
> Object value = valueStack.findValue(expression);
> Recommended implementation :
> String expression = field.getName();
> Object value = valueStack.findValue(expression);
> Reason:
> In JasperReports, a description of a field is just like a documentation for this field. So it may not good to use it as expression.
