I would suggest that you checkout trunk and then build the web site. The documentation on the combiners was improved to illustrate the difference between the OverrideCombiner, UnionCombiner, and a new MergeCombiner. The MergeCombiner may work the way you desire as it attempts to merge nodes rather than override them.

Also, after viewing that documentation, if you would like a combiner that works differently please open Jira issue that describes the way it should behave in detail. If you could provide a combiner that implements that, so much the better.

> When using OverrideCombiner it seems to ignore any list nodes and always return properties/values for list node from the overridden file. See the attached files for an example of what I mean. The following code always returns the values from config-custom even if list-nodes mentions that the sysprops node is a list-node.
> 		URL fileURL = TestConfig.class.getResource("config-conf.xml");
> 		
> 		try
> 		{
> 			DefaultConfigurationBuilder configBuilder = new DefaultConfigurationBuilder(fileURL);
> 			CombinedConfiguration config = configBuilder.getConfiguration(true);
> 			System.out.println(config.getString("sysprops/testkey"));
> 			System.out.println(config.getString("configprops/testkey1"));
> 		}
> 		catch (ConfigurationException e)
> 		{
> 			e.printStackTrace();
> 		}
