Hi Oliver,
Here is an exampe code:
{code}
CompositeConfiguration compositeConfiguration = new CompositeConfiguration();
compositeConfiguration.addConfiguration(new PropertiesConfiguration("props.properties"));

String[] values = compositeConfiguration.getStringArray("key1");
System.out.println(values); // "a, b, c,"
values = compositeConfiguration.getStringArray("key2");
System.out.println(values); // "a"
{code}

with
{code:title=props.properties}
key1 = a,b,c
key2 = ${key1}
{code}

I am expecting the get an array "a, b, c" for key2 but I get only "a"
thanks!
