All,

Wouldn't you know it, just after I posted, I had an epiphany:

On 5/13/2011 5:33 PM, Christopher Schultz wrote:
 entities
   entity
 foosome value/foo
 barsome other value/bar
 baz id=123 /
   /entity
 /entities

The solution is:

digester.addObjectCreate(entities/entity, Entity.class);

digester.addSetNestedProperties(entities/entity,
{ foo, bar, baz },
{ foo, bar, null }); // ignore baz

// go back and get baz
digester.addSetProperties(entities/entity/baz, id, baz);

Sorry for the noise.

Yeah, and probably more than one way even with out of the box rules:

  d.addObjectCreate(entities/entity, Entity.class);
  d.addCallMethod(entities/entity/foo, setFoo, 0);
  d.addCallMethod(entities/entity/bar, setBar, 0);
  d.addCallMethod(entities/entity/baz, setBaz, 1);
  d.addCallParam(entities/entity/baz, 0, id);

Thanks for the tip... that might actually be somewhat simpler code than
I have now. I'm using setNestedProperties and enumerating them because I
need to re-name some of the properties. But, that requires that I
enumerate all of them, even those I want to ignore, otherwise I'll get
an error. If I use addCallMethod, the Digester will probably ignore
anything for which there is no rule.

Thanks,

Hi Christopher,
I suggest you following Rahul's suggestion, SetNestedPropertiesRule is
not efficient as a direct invocation.
Moreover, for foo/bar properties, there's a 3rd way to set them:

 d.addObjectCreate(entities/entity, Entity.class);

 d.addBeanPropertySetter(entities/entity/foo);
 d.addBeanPropertySetter(entities/entity/bar);

 d.addCallMethod(entities/entity/baz, setBaz, 1);
 d.addCallParam(entities/entity/baz, 0, id);

HTH,
Simo
