GWT RPC requests fail in Opera when site has international domain name.

The error message is as follows:

Unable to initiate the asynchronous service invocation (GreetingService_Proxy.getDate) -- check the network connection

(DOMException) code: 12 INDEX_SIZE_ERR: 1 DOMSTRING_SIZE_ERR: 2 HIERARCHY_REQUEST_ERR: 3 WRONG_DOCUMENT_ERR: 4 INVALID_CHARACTER_ERR: 5 NO_DATA_ALLOWED_ERR: 6 NO_MODIFICATION_ALLOWED_ERR: 7 NOT_FOUND_ERR: 8 NOT_SUPPORTED_ERR: 9 INUSE_ATTRIBUTE_ERR: 10 INVALID_STATE_ERR: 11 SYNTAX_ERR: 12 INVALID_MODIFICATION_ERR: 13 NAMESPACE_ERR: 14 INVALID_ACCESS_ERR: 15 VALIDATION_ERR: 16 TYPE_MISMATCH_ERR: 17 SECURITY_ERR: 18 NETWORK_ERR: 19 ABORT_ERR: 20 URL_MISMATCH_ERR: 21 QUOTA_EXCEEDED_ERR: 22 TIMEOUT_ERR: 23 INVALID_NODE_TYPE_ERR: 24 DATA_CLONE_ERR: 25: SYNTAX_ERR

How could this be solved?

  • I suppose it fails with an error message? – Thomas Broyer Dec 04 '12 at 08:18
  • Yes, I have added it to the question. – Andrey Minogin Dec 04 '12 at 10:13
  • Which version of Opera are you using? Does a simple XMLHttpRequest works? E.g. in the console of Dragonfly `var xhr = new XMLHttprequest(); xhr.open('GET', window.location.href); xhr.send(); xhr.responseText` That code worked for me at one of http://idn.icann.org/#The_example.test_names in Opera 12.11.1661 on Linux x86_64 (Ubuntu 12.10) – Thomas Broyer Dec 04 '12 at 12:30
