I can confirm both OPA 10.4.1 and OPA Connector for Siebel 10.4.1 are being released at the same time, but I can't confirm it is happening this week. I will be posting release announcements when the public release occurs.
Long time no see! I am working for the Swedish Police (Siebel+OPA) and we are still on the fence about whether we can use 10.4 or should migrate the rulebase to 10.3 so that we can connect to Siebel. Is there an update on the timing of the release?
We can always leverage what I have done for web services until the connector is out ;) If it is for OWD then we need to wait for the connector.
Email me should you guys need a more indepth walkthrough.
