Oliver Heger commented on CONFIGURATION-481:
I am working on a fix (or better a re-implementation) based on the
{{ConfigurationInterpolator}} class and its feature to construct a chain of
interpolators. The idea is that {{DefaultConfigurationBuilder}} adds a special
parent interpolator to the configurations it creates which queries the newly
constructed {{CombinedConfiguration}}.
However, I must admit it is a mystery to me how this feature could work in the
past. (I also did not find any breaking change.) It was certainly an
undocumented feature which only worked by acciddent.

> With Commons Configuration 1.6, I was able to declare a variable in a
> properties file, and then reference it in a XML file using the $\{myvar\}
> syntax.
> For example:
> global.properties:
> {noformat}myvar=abc{noformat}
> test.xml:
> {code:xml}
>
>
> ${myvar}-product
>
>
> {code}
> config.xml:
> {code:xml}
>
>
>config-class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine"/>
>
> {code}
> When I try to retrieve the value, like so:
> {code}combinedConfig.getConfiguration("test").configurationAt("products/product[@name='abc']",
> true).getString("desc"){code}
> I get "$\{myvar\}-product" instead of "abc-product".
> This was working in Commons Configuration 1.6, but seems to be broken in 1.7
> and 1.8.
