Subject [jira] Updated: (CONFIGURATION-292) removeChild() doen't trigger auto saving
Date Sat, 11 Aug 2007 15:15:43 GMT

     [ https://issues.apache.org/jira/browse/CONFIGURATION-292?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Oliver Heger updated CONFIGURATION-292:
---------------------------------------

        Fix Version/s: 2.0
    Affects Version/s:     (was: Nightly Builds)
                       1.4

When directly accessing the nodes of a hierarchical configuration you circumvent all internal
update mechanisms. For normal operations you should not do that (why don't you call clearProperty()
or clearTree() instead?). The way hierarchical configurations are implemented at the moment
makes it very hard detect such direct changes on the raw data model.

Maybe this can be changed in a future release. We might for instance implement an event notification
mechanism that operates on a certain hierarchy of nodes. This will however involve incompatible
changes on classes and interfaces, so I am setting the fix version to the next major release.

> When I remove nodes from the XMLConfiguration with autoSave enabled the file doesn't
change. Here is an example 
> XMLConfiguration config = new XMLConfiguration("c:\\conf.xml"); 
> config.setAutoSave(true) ; 
> ConfigurationNode parentNode = config.getRootNode();
> parentNode.removeChild(childName);
> config.xml didn't change to reflect the changes
