I'm going to create a custom data type for my input fields. (see clas "Amount"). Setting the value in the inputfield "amountId" does work perfect. But, if i want to submit the form and go to another page, then i've got the "argument type mismatch" exception.
Can someone explain me, why i get this exception?
- Do i need a converter to convert the input value to string?
- Have i forgot some methods in my Amount class to implement, which JSF needs to get the values?
Here is my code:
public class Amount implements Serializable {
public Amount(BigDecimal bd){
}
public Amount(String s) {
}
@Override
public String toString() {
}
}
@ManagedBean(name="myBean")
@RequestScoped
public class MyBean extends BaseBean {
private Amount amountValue;
private UIInput amountValueId;
public Amount getAmountValue() {
return amountValue;
}
public void setAmountValue(Amount amountValue) {
this.amountValue = amountValue;
if (this.amountValueId != null)
this.amountValueId.setSubmittedValue(amountValue);
}
public UIInput getAmountValueIdId() {
return amountValueId;
}
public void setAmountValueId(UIInput amountValueId) {
this.amountValueId = amountValueId
}
}
<h:inputText id="amountValueId" binding="#{myBean.amountValueId}" size="30" value="#{myBean.amountValue}" />

I think you should add converter to your
<h:inputText
take a look at this Custom converter in JSF 2.0 cause your trying to submitString
intoAmount
