Hello Daniel,
this code really looks like there should be an easier solution to this. I
tried to get your code working in the playground but failed. Could you
perhaps explain what you want to achieve? Especially what data you want to
have in what property (label, model). If i have that, I think I could get a
compacter solution.
Best,
Martin
