I'm doing the following and it's just not working for me. I think I don't quite
understand how to use the @In annotation. Any suggestions? I apologize for the
long post, but I wanted to show the right amount of information. Thanks.
Here's the error...
javax.faces.el.EvaluationException: /calculator.xhtml @42,132
action="#{calculate.calculate}": javax.ejb.EJBException:
org.jboss.seam.RequiredException: In attribute requires value for component:
calculate.cb
Code looks like this...
@Name("calculate")
| @Stateful
| public class CaclulateAction implements Calculate {
|
| @In(create=true)
| private CalculatorBean cb;
|
| @DataModel
| private List<CalculatorBean> cbList;
|
| public String calculate() {
| double tmp = Math.pow(1. + cb.getGrowthRate() / 12., 12. * (cb.getEnd()
- cb.getStart()) + 1);
| double result = cb.getSaving() * 12. * (tmp - 1) / cb.getGrowthRate();
|
| cb.setResult(result);
| cbList.add(cb);
|
| return "/calculator.jsf";
| }
| }
simple bean to hold the data...
@Name("calculator")
| @Scope(ScopeType.CONVERSATION)
| public class CalculatorBean {
|
| getters/setters
| }
