Hi,
Here is all in nutshell:

TESTCASE:
package com.example;

public class CastorFooTest extends TestCase {
Mapping mapping = null;

}

}
public void testUnMarhallFoo() throws IOException, MappingException,

assertEquals(exp.getName(), result.getName());
}
private Foo getFoo(){
Foo foo = getFoo("");
Collection<Foo> children = new HashSet<Foo>();
children.add(getFoo("2"));
children.add(getFoo("1"));
foo.setChildren(children);
return foo;
}
private Foo getFoo(String s){
Foo foo = new Foo("foo".concat(s));
return foo;
}
private String expected = "<foo:foo
xmlns:foo=\"http://example.com/foo\"; name=\"foo\"><foo:children><foo:foo
name=\"foo1\"></foo:foo><foo:foo
name=\"foo2\"></foo:foo></foo:children></foo:foo>";
}
Expected output
<?xml version="1.0" encoding="UTF-8"?>
<foo:foo name="foo" xmlns:foo="http://example.com/foo";>
<foo:children>
<foo:foo name="foo1"/>
<foo:foo name="foo2"/>
</foo:children>
</foo:foo>
OUTPUT I GET:
<?xml version="1.0" encoding="UTF-8"?>
<foo:foo name="foo" xmlns:foo="http://example.com/foo";>
<children> - ERROR NUMBER 1
<foo:foo name="foo1">
<children /> - ERROR NUMBER 2
</foo:foo>
<foo:foo name="foo2">
<children /> - ERROR NUMBER 2
</foo:foo>
</children> - ERROR NUMBER 1
</foo:foo>
Output I get isn't valid:
1. <children> element must have foo prefix as all others: <foo:children>
2. there must not be empty <children/> element at all
Regards.

What version of Castor are you using ? And what does your mapping for the
relevant classes look like ? It looks like you are using the locations
attribute on the field mapping for the 'bar' children ?

Can you show us some sample XML that highlights your problem ? It just isn't
fully clear to me what the problem is.
