A new feature in OFM 12C is that you can track a Business flowinstance. I won’t go into the details as you can read all about it here. As this is a nice feature I was going to use this to set a good Flow instance name as descripted here in chapter 47.5.4 How to Set the Business Flow Instance Name or Composite Instance Name at Design Time. I created a simple service and added an assign in my mediator component as written in the documentation.
<assign> <copy target="$out.property.tracking.setFlowInstanceTitle" expression="oraext:setFlowInstanceTitle("Test")" xmlns:med="http://schemas.oracle.com/mediator/xpath"/> </assign>
As I added it, I noticed that the namespace declared here for the setFlowInstanceTitle wasn’t declared. I thought I would have have been declared somewhere else so I just tried it. As I compiled and deployed my service and ran the test I got the following error though:
ORAMED-01001:[Error in assign operation]Error occurred while assigning to target "$out.property.tracking.setFlowInstanceTitle" using expression "oraext:setFlowInstanceTitle('Test')".Possible Fix:Check if source message has right values or source expression is valid. Cause:Extension function error: Method not found 'setFlowInstanceTitle'
After some digging around and a chat with Oracle support it seems that
a) You have to add the namespace. It seems they forgot it in the online documentation. So the assign should look like this:
<copy target="$out.property.tracking.setFlowInstanceTitle" expression="oraext:setFlowInstanceTitle('Test')" xmlns:oraext="http://www.oracle.com/XSL/Transform/java/oracle.tip.pc.services.functions.ExtFunc" xmlns:med="http://schemas.oracle.com/mediator/xpath"/>
b) You have to apply patch 18310693 to the server. This means downloading it, unzipping and running the patch.

After this….start your server again and try your composite again. The result should be:
