Sorry, I misspoke. Each part of choreography task has to be separated from the other. There will be the possibility to select all three parts of the choreography task and then write its own label. The behavior is the same of participants and lanes when there are more than one lanes.
I searched in “BpmnRenderer.js” and in “ElementFactory.js”, but can’t find the useful functions to obtain the desired result.
Where can I find some useful functions?
