Thorbjørn Ravn Andersen commented on CONFIGURATION-288:
-------------------------------------------------------

Code snippet (GetNestedConfigurationName.java)

package x;

import org.apache.commons.configuration.CombinedConfiguration;
import org.apache.commons.configuration.Configuration;
import org.apache.commons.configuration.DefaultConfigurationBuilder;
import org.apache.log4j.BasicConfigurator;

public class GetNestedConfigurationName {

	public static void main(String[] args) {
		try {
			main0(args);
		} catch (Throwable e) {
			e.printStackTrace();
		}
	}
	public static void main0(String[] args) throws Exception {
		BasicConfigurator.configure();
		DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder("A.xml");
		Configuration configuration = builder.getConfiguration();
		System.out.println("C is loaded : c.property1=" + configuration.getString("c.property1"));
		if (configuration instanceof CombinedConfiguration) {
			CombinedConfiguration combined = (CombinedConfiguration) configuration;
			Configuration c = combined.getConfiguration("C");
			if (c == null) {
				System.out.println("no configuration named C");
			} else {
				System.out.println("C by name : c.property1=" + c.getString("c.property1"));
			}
		}
	}

}

output is

C is loaded : c.property1=value1
Combined configuration
no configuration named C

>                 URL: https://issues.apache.org/jira/browse/CONFIGURATION-288
>             Project: Commons Configuration
>          Issue Type: Bug
>    Affects Versions: Nightly Builds
>         Environment: using trunk of august 6 2007
>            Reporter: Thorbjørn Ravn Andersen
>         Attachments: A.xml, B.xml, C.properties, GetNestedConfigurationName.java, namedConfiguration.jar
>
>
> Given a <configuration> A which includes a <configuration> B which in turn
loads the <properties> C.
> A and C has the config-name attribute.  B does not.
> Calling A.getConfigurationNames() does not return the name of C.  From my initial reading
of the code, it only returns names on the B level.
> It also appears that the name for A does not appear either.
