The workspace link of a pipeline job has a link to the workspaces used in the last build. Great !
But, in a job, I can see 3 lines with a link to the same place, but with 3 different link like :
${BUILD_URL}/execution/node/number ???>/ws/
I did not know what is this number ????. But i nspecting the build directory, it seems that thesolution i sin the flowNodeStore.xml file.
Each number on a link is related to a <String><number>.</String> followed by a label directive. E.g.
<string>73</string>
<string>72</string>
<string>label</string>
<string>RaspPi</string>

And for the corresponding build, I have a workspace link node/73/ws/
The same pattern applies for the two others.

It would be clearer and less user disturbing to have only one link.
