The final 2 default converters are for maps and collections:
<convert converter="collection" match="java.util.Collection"/>
<convert converter="map" match="java.util.Map"/>
Generally speaking these converters will be able to recursively convert their contents.
There is a catch for these 2 however:
Since we can't work it out automatically we may need to use the special signatures syntax in the dwr.xml file to allow us to hint types to the conversion process.
Maps and null keys
<convert converter="map" match="java.util.Map"> <param name="nullKey" value="null"/> </convert>
