Hi,
maybe this is a typo, but the problem seems to be in the last while()
loop of your test program:
> SubnodeConfiguration c2 =
> configuration.configurationAt("environments/[EMAIL PROTECTED]'dvl9']");
> Iterator keys2 = c2.getKeys();
> while(keys2.hasNext()) {
> String next = (String) keys2.next();
> System.out.println(next + " = " +
configuration.getList(next));
> }
Instead of
configuration.getList(next);
it should be
c2.getList(next);
I hope this is all!

Hi,
I am trying to migrate to commons configuration for all the usual
reasons, but have run into the following problem which I would
appreciate if a more knowledgeable person than me would glance at. I
want to migrate a set of property files into a single XML-file to have a
more maintainable system, while keeping the code as similar as possible.
The following code gives me an incorrect result:
SubnodeConfiguration c2 =
configuration.configurationAt("environments/[EMAIL PROTECTED]'dvl9']");
The keys appear to be correct of c2, but the values are all empty.
This is against SVN of today, as the 1.3 release hits a JIRA.

I would appreciate any pointers and hints helping me figuring out what I
have misunderstood.
