[configuration] Issues with XMLConfiguration

["Klein, Raimund" <Ra...@berenberg.de>]

Hi everyone,
 
I've been playing around with configuration 1.7 for a while now, specifically XMLConfiguration (since I'm a fan of hierarchical files) and the XPathExpressionEngine. Cool stuff. :-)
 
However, I've run into two issues:
- Since my file is nested a couple of levels, I like to create configuration nodes with children myself and then add whole subtrees at the appropriate points. For the self-created nodes, I rely on org.apache.commons.configuration.tree.DefaultConfigurationNode. I also like the SubnodeConfiguration class while working on the subtree. However, I've found that when really adding new nodes to the configuration, I can't simply add them to a matching SubnodeConfiguration, as they won't be converted into XML Nodes, which causes possible ClassCastExceptions later on. Instead, I have to add them to the XMLConfiguration directly. This is due to the fact that XMLConfiguration overrides addNodes(String, Collection) and converts the nodes in the Collection into its own XML nodes; however, SubnodeConfiguration of course doesn't do this. I've been wondering whether this is intentional or maybe I'm completely missing the idea of the class SubnodeConfiguration itself. Maybe XMLConfiguration's configuration(s)At methods should return a subclass of SubnodeConfiguration which will perform the same node conversion?
 
- Is there a way to assign a formatter to changed XMLConfigurations when saving? I've found inspecting and maybe even changing the stored configuration files by hand a bit cumbersome, as there is apparently no such thing as auto-indent. As I'm expecting my files to grow over time, this would come in quite handy.
 
Other than that, I'm quite happy with what I've found so far. :-)

Mit freundlichen Grüßen / Kind regards

Hello Raimund,

's configuration(s)At methods should return a subclass of SubnodeConfiguration which will perform the same node conversion?

This is not by intension, it is rather a missing feature (well, maybe 
even a bug). Could you please open a ticket in our bug tracking system 
[1] for this? It's a good idea to let XMLConfiguration return a specific 
SubnodeConfiguraition with an overridden createNode() method.

Unfortunately, there is no support for formatting yet. This would 
certainly be a nice new feature. However, I am not sure what would be a 
suitable interface for such a formatter?

Thanks
