Re: [configuration] Variable Interpolation doesn't happen in subset() and configurationAt()

[Oliver Heger]

Mark,

I can now reproduce the problem. In this code fragment you call subset() 
rather than configurationAt(), and here interpolation fails. I have 
created a bug report for this problem [1].

Thanks
Oliver

heres more detail:

my instatiation of Configuration looks more like this

CombinedConfiguration configuration = new CombinedConfiguration();
configuration.addConfiguration(
                new PropertiesConfiguration(new
File(configProperty).toURL())
            );


My properties file looks like this:

# DSpace installation directory
dspace.dir = /dspace
# Example Apache HTTPD configuration
# config.template.apache13.conf = ${dspace.dir}/config/httpd.conf
config.template.log4j.properties = ${dspace.dir}/config/log4j.properties
config.template.log4j-handle-plugin.properties = ${dspace.dir
}/config/log4j-handle-plugin.properties
config.template.oaicat.properties = 
${dspace.dir}/config/oaicat.properties


I then go on to do my test:


        System.out.println(configuration.getString("dspace.dir"));
        System.out.println(configuration.getString("
config.template.log4j.properties"));
        System.out.println(configuration.getString("
config.template.log4j-handle-plugin.properties"));
        System.out.println(configuration.getString("
config.template.oaicat.properties"));

        Configuration subset = configuration.subset("config.template");

        this.assertEquals(
                    configuration.getString("
config.template.log4j.properties"),
                    subset.getString("log4j.properties")
                    );

        this.assertEquals(
                configuration.getString("
config.template.log4j-handle-plugin.properties"),
                subset.getString("log4j-handle-plugin.properties")
                );

        this.assertEquals(
                
configuration.getString("config.template.oaicat.properties
"),
                subset.getString("oaicat.properties")
                );



Thanks,
Mark
