Subject RE: Copying appenders and loggers from a confgiruation to a builder
Date Thu, 17 Nov 2016 17:41:40 GMT
I don't think I'm able to do so.  Although I set up an account on the JIRA and have logged
in, the only thing I'm allowed to "Create" is a "Service Desk Request".  There is nothing
there about reporting a bug, requesting a feature, etc.

CompositeConfiguration does not help either.  My use case doesn't seem to be supported.  I
don't want to programmatically create a configuration.  I want to combine configurations and
output the combined config to disk.  Then that can be passed in as the new configuration.

The only thing that can generate XML is a ConfigurationBuilder.  But there is no way to transfer
loaded Configurtations to a Builder nor as there a way to generate XML from a built configuration.

Please feel free to record your feature request in JIRA:
