Subject [jira] Updated: (BETWIXT-63) Writing Map key/value pairs produces incorrect XML tags

Pete Ford updated BETWIXT-63:
-----------------------------

    Description: 
Using download version 0.8.

A Map field within a Javabean produces XML containing Key and Value tags by default (i.e.
without a .betwixt file):

Java:

private Map<String, String> details = new TreeMap<String, String>();

Example XML output:

<Details>
  <entry>
    <Key>...</Key>
    <Value>...</Value>
  </entry>
</Details>

When reading the generated XML back into Betwixt to reconstruct the bean, the map is not populated.
It appears that when reading, Betwixt looks for the tags <key> and <value> (uncapitalized).
Filtering the XML to replace <Key> with <key>, etc., before reading in fixes the
problem. It would appear that Betwixt should be generating "<key>" and "<value>"
when writing (to match the case of the enclosing "<entry>" tag). Possibly this is something
to do with using Capitalized names (see the code below - it sets up a CapitalizedNamesMapper
for element names).

The code that configures the writer in this case is:

        StringWriter sw = new StringWriter();
        BeanWriter writer = new BeanWriter(sw);
        writer.getXMLIntrospector().getConfiguration()
                .setAttributesForPrimitives(true);
        writer.getXMLIntrospector().getConfiguration()
                .setWrapCollectionsInElement(true);
        writer.enablePrettyPrint();
        writer.getBindingConfiguration().setMapIDs(false);

        // set a custom name mapper for attributes
        writer.getXMLIntrospector().getConfiguration()
                .setAttributeNameMapper(new HyphenatedNameMapper());

        // set a custom name mapper for elements
        writer.getXMLIntrospector().getConfiguration()
                .setElementNameMapper(new CapitalizeNameMapper());

[EDIT:]

Tested the above code changing it so that it uses DecapitalizeNameMapper and also HyphenatedNameMapper
for the element names. In both cases the key/value tags are rendered lowercase and behave
correctly on readback.
