Re: Populate ListButton with enum data binding ?

[Roger and Beth Whitcomb]

That is a really good question, Josh.  My first thought is that you will 
probably have to populate the list in Java code.  My second thought is 
to poke through the BXMLSerializer code to see it I can figure it out.  
But, what was the complete stack trace of the SerializationException 
(i.e., the cause).  That could point the way to a solution.  But, at the 
moment I don't know the answer.

Thanks,

I'm having an issue doing data binding with bxml.  My app has a Dialog 
with a Form that shows a lot of editable fields for an object.  Using 
form.load(new BeanAdapter(myObject)) is working for most of the fields 
(TextInput and Checkbox) but I'm having trouble with ListButton.  I 
want to populate the listData with values from an enum and then set 
the selected item from a myObject value. I can't figure out how to 
specify the enum for the list data in the bxml. I think I'm close:

(simplified example to mirror actual app)

public class Paint {
   public enum Color { RED, BLUE, GREEN }
}

public class Car {
    private Paint.Color color;

    public Paint.Color getExteriorColor() { return color; }
    public void setExteriorColor(Paint.Color color) { this.color = 
color; }
}

<ListButton selectedItemKey="exteriorColor">
    <listData>
        <collections:EnumList>
     <!-- how do I specify constructor parameter Paint.Color class 
here? -->
        </collections:EnumList>
    </listData>
</ListButton>


I tried 'enumClass' as an attribute of <EnumList> and a child element, 
but I always get an 
"org.apache.pivot.serialization.SerializationException" on the line 
with <collections:EnumList>
