Oliver Heger commented on CONFIGURATION-504:
--------------------------------------------
Just to make sure I understand your problem correctly: You have a hierarchical
configuration and call {{configurationAt(key)}} with some key to obtain a sub
configuration. Then on this sub configuration you invoke {{clear()}}. Now your
expected result is that the whole node with the given key is removed from the
original hierarchical configuration, right?
> HierarchicalConfiguration clear() method doesn't remove the node from its
> parent anymore in XML source

> Key: CONFIGURATION-504
> URL: https://issues.apache.org/jira/browse/CONFIGURATION-504
> Project: Commons Configuration
> Issue Type: Bug
> Affects Versions: 1.8
> Reporter: Adrien CLERC
> Priority: Minor
>
> Using an XML source file, I used to call HierarchicalConfiguration.clear() on
> an object to remove it from its parent. Now, it just clear the text and the
> subnodes, but not the node itself, nor its own attribute, when the file is
> saved.
> Here is the code that works :
> {code}
> ConfigurationNode oldNode = configuration.getRootNode();
> oldNode.getParentNode().removeChild(oldNode);
> {code}
> configuration belong to a list of HierarchicalConfiguration that I obtained
> from configurationsAt. I didn't see any other way to remove a node I got from
> that method, without explicit casting to SubnodeConfiguration.
