Raimund Klein updated CONFIGURATION-472:
----------------------------------------

    Description: 
Problem description: XMLConfiguration's configuration(s)At return regular SubnodeConfigurations which can't "really" be used for adding nodes as these won't be converted into XMLConfiguration's internal XMLNodes. More precisely, when using the SubnodeConfiguration for adding, accesses to the main XMLConfiguration can run into ClassCastExceptions later on.

Workaround: Add the created nodes directly to the main XMLConfiguration (e.g. with the appropriate XPath), as this configuration's add methods convert these into the internal form.

Proposed Solution: Let XMLConfiguration's configuration(s)At methods return a subclass of SubnodeConfiguration whose add methods will perform the same node conversion. Consequently, this new class' SubnodeConfigurations returned by configuration(s)At should be instances of the very same class.
