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.
