Oliver, that is great news! I'll check out the latest version to play
with. What is the release plan?

Yes, I plan to support names for configurations. But this is one of the
things that are not implemented yet.

Hi,
I did not find the time yet to test 1.3-dev, but I have a question. If
have a configuration.xml such as
<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
<properties fileName="foo.properties"/>
<properties fileName="bar.properties"/>
<properties fileName="acme.properties"/>
<xml fileName="cow.xml"/>
<xml fileName="chicken.xml"/>
</configuration>
then I find these lines in my code:
public static CompositeConfiguration config;
....
// WARNING - acme.properties must be 3rd entry in configuration.xml
Configuration propertyConfiguration = config.getConfiguration(2);
Will there be a way to get propertyConfiguration (or xmlConfiguration or
even (!) databaseConfiguration) out of configuartion.xml _by some id_
and _not by index_? I don't want my application stop working just
becouse someone changed the order of elements in configuration.xml.
Regards,
Borut

It would be great if somebody could test these new features. So far we
have not got any feedback.
A new release has not been discussed yet. Don't know about the other
committers, but I have some things on my list I would like to finish
before a new version. This is especially the re-design of the
ConfigurationFactory class. I started with an alternative implementation
(called DefaultConfigurationBuilder), which is quite functional ATM, but
some things are missing.
