The next release will contain an alternative class called
DefaultConfigurationBuilder. This class works very similar to
ConfigurationFactory, but provides true hierarchical processing.
ok, i got the rc, and tried the following:
DefaultConfigurationBuilder builder = new DefaultConfigurationBuilder();
try {
builder.setFile(new File("config.xml"));
CombinedConfiguration conf = builder.getConfiguration(true);
} catch (ConfigurationException e) {
e.printStackTrace();
}
i used the xml-files from my OP and got the same result.
what would be the best (or working) :) solution for the following problem.
i want a central configuration file, where i can include other
configurations-files.
the other included configurations should not be merged, but be a huge
union, so _no_ value gets overriden by an other, and i can access all
values.
thank you,

I think I know now what the problem is: the configuration key in the
expression if(!conf.containsKey("a.b("+i+")")) is evaluated as (a).b(i)
and not as (a.b)(i).
Because there is no <a> element in your example xml files that has more
than 4 <b> sub elements the condition results to false for i >= 4. In
your case (when you are not interested in the hierarchical structure and
simply want to query all existing <b> elements) you can do:
List values = conf.getList("a.b");
The returned list will contain the values of all existing <b> elements.
I tested this with DefaultConfigurationBuilder. I suppose it will work
with ConfigurationFactory, too.
