Question

I’m trying to compare two different object in JSF.
A String and an Integer, of cours it don’t work…

//myVar ==> Integer object
//myVar2 ==> String

<c:if test="${myVar == myVar2}">
    YES!!!!!!!!
</c:if>

I try with myVar.toString but it’s wrong.
So how to do it ?

Thank’s

That does not sound right – I would check the values. For the bean:

public class CoercedBean {

  public int getValueAsInt() {
    return 123;
  }

  public String getValueAsString() {
    return "123";
  }

}

…these example expressions evaluate to true:

${coercedBean.valueAsInt == coercedBean.valueAsString}
<h:outputText style="color: blue"
    value="#{coercedBean.valueAsInt eq coercedBean.valueAsString}" />

The JSP 2.1 (EL) spec says of evaluating equality:

A {==,!=,eq,ne} B

If A or B is Byte, Short, Character,
Integer, or Long coerce both A and B
to Long, apply operator
