Trace from Relationship Field
I have nodes from two different documents. The nodes are different types. We'll call them Requirement A and Test Case B.
Test Case B was traced to Requirement A by doing the normal alt+click on Test Case B and then drag and drop onto Requirement A. This worked fine and shows Test Case B in the "Verified By" field on Requirement A.
Next I want to trace Test Case B onto another Requirement in the same document as Requirement A. We'll call this one Requirement C. To do this, I select Test Case B from the "Verified By" relationship field on Requirement A and then do the alt+click and drag and drop. When I drag it over Requirement C, it shows the "Create trace" tool tip. But when I drop it, I get an error that says:
"MKS124719: The specified item 1,234,567 is not a segment. It is an item of type Test Case."
In the client log, I see the error right after:
at mks.ic.ci.commands.InsertSegmentCommand.doExecute(InsertSegmentCommand.java:52)
Why is it trying to do an insert segment? What I expected it to do was create a trace between Requirement C and Test Case B. I believe I used to be able to perform this action with an older version of the client. We are currently using client version 11.2.
These nodes are not actually requirement and test case. They are custom node types that we have created. Neither one acts as a test case.
