Variable interpolation across files broken in 1.7 & 1.8
-------------------------------------------------------
Key: CONFIGURATION-481
URL: https://issues.apache.org/jira/browse/CONFIGURATION-481
Project: Commons Configuration
Issue Type: Bug
Components: Interpolation
Affects Versions: 1.8, 1.7
Environment: Any OS, but have verified with Windows 7 and AIX 6.1,
running Java 1.6.0.
Reporter: Jim Prantzalos
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 ${myvar} syntax.
For example:
global.properties
-----
myvar=abc
test.xml
-----
<products>
<product name="abc">
<desc>${myvar}-product</desc>
</product>
</products>
config.xml
-----
<properties fileName="global.properties"/>
<xml fileName="test.xml" config-name="test">
<expressionEngine
config-class="org.apache.commons.configuration.tree.xpath.XPathExpressionEngine"/>
</xml>
When I try to retrieve the value, like so:
combinedConfig.getConfiguration("test").configurationAt("products/product[@name='abc']",
true).getString("desc")
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.
