[webUI] Easy Test Case results in cyclic configuration graph #29

kvndrsslr commented 3 years ago

Problem

Attempting to create a very minimal test results in the webUI generating an erroneous cyclical graph.

Input hello.ttl

<urn:test:a> <urn:test:b> <urn:test:c> .
<urn:test:a> <urn:test:d> <urn:test:c> .

webUI configuration:
