Description

This issue can be easily reproduced!
Create a configuration files like this:
config.xml:

<?xml version="1.0" encoding="ISO-8859-1" ?>
<configuration>
	<system />
	<xml  fileName="myproperties.xml" config-name="properties" />
</configuration>

<?xml version="1.0" encoding="UTF-8"?>
<properties>
	<colors.pie>#FF0000, #00FF00</colors.pie>
</properties>

Java code:

DefaultExpressionEngineSymbols symbols = new DefaultExpressionEngineSymbols.Builder(
				DefaultExpressionEngineSymbols.DEFAULT_SYMBOLS)
// Use a slash as property delimiter instead of dot
				.setPropertyDelimiter("/").create();

DefaultExpressionEngine engine = new DefaultExpressionEngine(symbols);

// Now create a configuration using this expression engine
Parameters params = new Parameters();
DefaultListDelimiterHandler listDelimiterHandler = new DefaultListDelimiterHandler(',');
XMLBuilderParameters xmlBuilderParameters = params.xml()				.setFileName("config.xml").setExpressionEngine(engine)				.setListDelimiterHandler(listDelimiterHandler);
dcb = new CombinedConfigurationBuilder().configure(xmlBuilderParameters);
try {
	config = dcb.getConfiguration();
	} catch (ConfigurationException e) {
	        // TODO Auto-generated catch block
		e.printStackTrace();
}

I could not retrieving values of colors.pie using:
config.getStringArray("colors.pie");
The result is a single string "#FF0000, #00FF00" instead of an array of Strings.
However, using Java code to add a new property like this:
config.addProperty("my.test.value", "#FF0000, #00FF00"),
I can get an array as the result of :
config.getStringArray("my.test.value");
