OFM 12C from the trenches: Business flow instance name bug and solution

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.


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:


b) You have to apply patch 18310693 to the server. This means downloading it, unzipping and running the patch.

OPatch detects the Middleware Home as "C:\Oracle\Middleware\Oracle_Home"

OPatch succeeded.

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