[jira] [Commented] (CONFIGURATION-504) HierarchicalConfiguration clear() method doesn't remove the node from its parent anymore in XML source

["Oliver Heger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-504?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13439779#comment-13439779 ] 

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?

> 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.
