No. You would have to look at how HierarchicalConfiguration differs
and create a patch. IIRC the problems were confined to that one class.

Hi Ralph,
Thanks for the fast response! I just checked out the trunk and built
the
jar, and it is indeed now saving the file successfully. Do you know
of any
possible workarounds with version 1.6 release?
Thanks again,
Jonathan

Actually, I take it back. I think I already fixed this. Can you
check out
trunk and see if you still have the same problem?

Hi,
I am using the CombinedConfiguration class to combine two
XMLConfigurations
and trying to save the result as xml. My code is as follows:
CombinedConfiguration cc = new
CombinedConfiguration(new
OverrideCombiner());
cc.addConfiguration(firstXMLConfig);
cc.addConfiguration(secondXMLConfig);
combinedConfig = new XMLConfiguration(cc);
combinedConfig.save("path/to/file.xml");
When I try to do the save operation however, I am getting the
following
exception:
Caused by: java.lang.ClassCastException:

It looks like ViewNode is created when firstXMLConfig and
secondXMLConfig
have a node with the same key in the combine process. Is there a
way to
convert all ViewNodes into HierarchicalConfiguration.Node? Or am I
using
this incorrectly?
Thanks,
Jonathan
