[castor-user] Unmarshal Java 5 enum

[rliou]

I am trying to un/marshal objects of a class with a member of an enum type, as 
described below.

public enum Color {
    RED("R"), GREEN("G"), BLUE("B");
    private String value;
    private Color(String v) {
        value = v;
    }
    public static fromValue(String v) {
        for (Color c : Color.values()) {
            if (c.value.equals(v)) {
                return c;
            }
        throw new IllegalArgumentException(v);
    }
    public String value() {
        return value;
    }
    public String toString() {
        return value;
    }
}

public Test {
    Color color = RED;
    public Color getColor() {
        return color;
    }
    public void setColor(Color c) {
        color = c;
    }
}

With XML mapping:

<class name="package.Test">
    <map-to xml="Test"/>
    <field name="color" type="package.Color">
        <bind-xml name="color" node="element"/>
    </field>
</class>

I am able to marshal objects of Test. However, I get exceptions when I 
unmarshal the output file.

java.lang.IllegalArgumentException: No enum const class package.Color.R

The debugger shows that the method Color.valueOf is called instead of 
Color.fromValue. How do I make Unmarshaller to call Color.fromValue? What did I 
do wrong here? Please help.
Thank you.
