Subject [betwixt][BUG?] Destreaming custom collections using Hyphenated/DecapitalizeNameMapper?
Date Sat, 14 Dec 2002 08:49:58 GMT
Hi people,
    I am trying to destream some XML using betwixt into a class structure
which looks like:

public class Foos {
    // manages a collection of Foo
    public void addFoo(Foo foo) { ... }
    public Iterator getFoos() { .... }
}

public class Foo {
    // ...
    public void setValue(String value) { ... }
    public String getValue() { ...}
}

Using the DefaultNameMapper, this streams as:

<Foos>
  <foo value="a"/>
  <foo value="b"/>
</Foos>

and destreams fine. However with the Hyphenated/DecapitalizeNameMappers,
it doesn't destream correctly - the addFoo() method is not invoked.
Streamed it looks like:
<foos>
  <foo value="a"/>
  <foo value="b"/>
</foos>

Looking at the debug trace, the following messages from XMLIntrospector
appear:
....
Processing child ElementDescriptor[qname=foos,pname=foos,class=interface
java.util.Iterator,singular=class Foo,updater=MethodUpdater [method=public
void Foos.addFoo(Foo)]]

Creating generic rule for recursive elements
^^^^^^^^^^^^ problem starts here^^^^^^^^^^^^

Created bean create rule
Descriptor=ElementDescriptor[qname=foos,pname=foos,class=interface
java.util.Iterator,singular=class Foo,updater=MethodUpdater [method=public
void Foos.addFoo(org.apache.commons.sql.type.Foo)]]
Class=class Foo Path prefix=*/foos
Ignoring duplicate digester rule for path: */foos rule: BeanCreateRule [path
prefix=*/foos
descriptor=ElementDescriptor[qname=foos,pname=foos,class=interface
java.util.Iterator, ....

I'm configuring the introspector using:

        introspector.setAttributesForPrimitives(true);
        introspector.setWrapCollectionsInElement(false);
        introspector.setElementNameMapper(new DecapitalizeNameMapper());

Any ideas/workarounds?

Thanks,

Tim
