Two pipeline jobs were created, 

Job 1, named TEST_PIPELINE, pipeline script content:

stage ('testing') {
{{ build job: 'TEST_PIPELINE_2', wait: true, propagate: false }}
}

Job 2, named TEST_PIPELINE_2, pipeline script content

stage ('testing') {
{{ println ('Hello world!') }}
}

Test execution:

1. Start manually the job TEST_PIPELINE

Expected result:

1. TEST_PIPELINE Job is executed correctly, triggering the TEST_PIPELINE_2 Job -> OK
2. TEST_PIPELINE_2 is executed correctly -> OK
3. Information about the triggering is shown in the TEST_PIPELINE console information -> OK
4. Job information in TEST_PIPELINE shows the Downstream job information -> Not OK: no information about downstream job is shown
   1. Build result shows the downstream job information -> Not OK: only way to check that a job was triggered is through the console
5. Job Information in TEST_PIPELINE_2 shows the Upstream job information -> Not OK: not information about upstream job is shown
   1. Build result shows the upstream job information -> Not OK, but that information is shown in the "triggering" information section

That feature is working if you are not using pipelines, I do not know why it is not working in my setting: maybe I am missing a parameter, or a plugin, but googling for it delivered no results

I expected the list of upstream/downstream jobs to be correctly filled, what in my case, is not happening
