Hello! My WSDL was incorrect. I read RFC and found several errors. After fix all work fine.

[ngnpope]

Can you confirm that the example at http://slednev.ru/example.wsdl is still incorrect then?

[russian-developer]

Yes! I'm didn't fix it.

Just wanted to mention that a different problem existed before e04a585 so no regression in functionality (even though it's clearly a bug).
