Show us your CalculatorController class

[keeve]

Here it is:

@Name("CalcBean")
@Scope(ScopeType.CONVERSATION)
public class CalculatorController {

 /** Creates a new instance of CalculatorController */

 public CalculatorController() {
 }

 private Calculator cal = new Calculator();
 private int num1 = 0;
 private int result = 0;
 private int num2 = 0;

 @Create
 @Begin(pageflow="CalcBean")

 public void setCalculator(Calculator aCal){
 this.cal = aCal;
 }


 public void setnum1(int num_1){
 this.num1 = num_1;
 }

 public int getnum1(){
 return num1;
 }

 public int getResult(){
 return result;
 }
 public void setnum2(int num_2){
 this.num2 = num_2;
 }

 public int getnum2(){
 return num2;
 }

 public void add(){
 result = cal.add(num1, num2);

 }

 public void multiply(){
 result = cal.multiply(num1, num2);

 }
}

...and now show us the home.xhtml ;-)

You are passing in a seam component into a setter expecting a Calulator. A converter missing?
