the namedspace array gets filled in the order of registration of the namespaces only idx 0 and 1 are stable!

clients need to be aware of that and should always store uris (expanded nodeids) instead of the idx... or the namespace array alongside the nodeids, so it can be translated and checked against the server after connect.

Yes, I am of exactly the same opinion.

For this reason, i thought using the NamespaceIndex instead of the Uri when creating the classes in the ua module could be a problem. However, the NamespaceArray is kept in every ua.Client() and could therefore be used for translation. But Im not sure if this is the case and could be the reason for my error described above
