Hi,
getProperty() always returns the raw value, to get the interpolated
value you have to call getString() (or another getter).

Hi there! I'm trying to get Variable interpolation to work. But it seems
that either I missed something at the docs or there's a bug here.
All I need is to replace a ${app} on my properties file to contain a string
instead
so whenever I have ${app}.maxUsers=10 I want AppName.maxUsers=10
Here's some code:
private class AppInterpolator extends StrLookup{
@Override
public String lookup(String var) {
return "#{"+appName+"}";
}
}
ConfigurationInterpolator.registerGlobalLookup("app", new
AppInterpolator());
config = new CompositeConfiguration();
PropertiesConfiguration localProps = new
PropertiesConfiguration(this.getClass().getClassLoader().getResource(PROPERTIES_FILE_NAME));
this.config.addConfiguration(localProps);
But after using config.getProperty("") I've noticed that the property here
is ${app}.maxUsers and not AppName.maxUsers
I've also noticed that it seems that PropertiesFile does not reference
ConfigurationInterpolator at all.
Any ideas on how to fix this?
Regards
