DWR - can't marshall enum?

No matter what I try, this keeps f开发者_开发知识库ailing. What am I doing wrong, here?

package com.example
class ClassToMarshall{
   SomeEnum myEnum
}

enum SomeEnum{
A,
B
}

resources.xml:

   <dwr:configuration>
        <dwr:convert type="bean" class="com.example.**">
            <dwr:exclude method="metaClass"/>
        </dwr:convert>
        <dwr:convert type="enum" class="com.example.SomeEnum">
            <dwr:exclude method="metaClass"/>
        </dwr:convert>
    </dwr:configuration>

However, when I call MyService.myMethod({myEnum: "A"}), I'm receiving Throwable throwable. What's going on?

That's all correct. If you have some other exception, you'll get the generic Error error prompt unless you enable marshalling of exceptions.

If you add this to your configuration:

<dwr:configuration>
    <dwr:convert class="java.lang.Exception" type="exception"/>
    <dwr:convert class="java.lang.StackTraceElement" type="bean"/>
</dwr:configuration>

You'll probably see an error that isn't marshalling related.
