First, I'm new to Betwixt, but by no means new to the Digester.  I've
used the Digester successfully for several projects.
 
I'm having a problem.  I cannot figure out how to have my existing xml
be read/written properly (without a betwixt file), when my XML root
element already contains an attribute @id and also has (what Betwixt
classifies as a 'primitive') an element <name>, which is a String.  For
example:
 
<customer id="111">
       <name>XYZ LLC</name>
</customer>
 
Tester:
 
BeanReader reader = new BeanReader();               
XMLIntrospector x =  new XMLIntrospector();
            x.setElementNameMapper(new DecapitalizeNameMapper());
            x.setAttributesForPrimitives(false);                      
reader.setXMLIntrospector(x);
reader.registerBeanClass( Customer.class );        
 
 
The problem lies in the x.setAttributesForPrimitives(true);.  This works
for @id, but not for <name>, or vice versa when set to false when
Customer.java is:
 
public class Customer{
 
            private String id;
            private String name;
 
            .
}
 
I know I can do the following and make it work, but this is somewhat
bothersome since I have to do this for every entity with an id:
<?xml version="1.0" encoding="UTF-8"?>
<info primitiveTypes="element">
       <element name="customer">
             <attribute name="id" property="id"/>
             <addDefaults/>
       </element>
</info>
 
 
How can I get both @id and <name> to be read/written properly
programmatically, exactly as the source file shows?   It would be easier
for me to specify an AttributeDescriptor generically, instead of
providing a betwixt file for all of them.
 
Am I missing something here?
 
Thanks,
 
Kevin Ross
