AIA Composite (Requestor ABCs) with empty main sequence

In AIA Service Constructor, when I was generating Requester ABCS, pretty much everything went fine except one step where it is very easy to make mistake and it can create composite with with empty sequence.

Step 6 of service constructor, we must select "Target is an Enterprise Business Service" as shown below:




Majority of the time it defaults to "Target is an Application Integration..", and if we select that option, it creates requestor ABCS composite with empty main sequence, and it looks like this:



So solution is quite simple, just change it back to "Target is enterprise Business Service".
