----------------------------------------------
Patched into 1.8 and rebuilt. Works great. Thank you!

> Project: Commons Configuration
> Issue Type: Bug

> Affects Versions: 1.7, 1.8
> Environment: Any OS, but have verified with Windows 7 and AIX 6.1,
> running Java 1.6.0.

> 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 $\{myvar\}
> syntax.
> For example:
> global.properties:
> {noformat}myvar=abc{noformat}
> test.xml:
> {code:xml}
> <products>
> <product name="abc">
> <desc>${myvar}-product</desc>
> </product>
> </products>
> {code}
> config.xml:
> {code:xml}
> <properties fileName="global.properties"/>
> <xml fileName="test.xml" config-name="test">
> <expressionEngine
> config-class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine"/>
> </xml>
> {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.
