Scott Wells commented on CONFIGURATION-342:
-------------------------------------------

Okay.  I'm pretty slammed with major release planning at work right now after presenting several successful proof-of-concept projects.  I'm 99.999% sure that we'll be using Commons Config, and in particular DatabaseConfiguration for shared persistent storage and XMLConfiguration for externalized format (for import/export, revisioning through SCM, etc.).  As we get into the productization of that, I'll likely ping you again to chat about how DatabaseConfiguration might evolve to have the same level of expressiveness as HierarchicalConfiguration and what we might do to aid in getting it there.

> I've found a bug where adding a list property to a BaseConfiguration, then copying that full BaseConfiguration to a DatabaseConfiguration, the list is lost and only the first element is copied to the destination DatabaseConfiguration.  For example:
> BaseConfiguration bc = new BaseConfiguration();
> bc.addProperty("myList", Arrays.asList("1", "2", "3", "4");
> DatabaseConfiguration dc = new DatabaseConfiguration(...);
> dc.copy(bc);
> List list = dc.getList("myList");
> // At this point, you'll get a single element list containing only "1"
