Your code looks good. > (This means other types in my project affected by this problem too but its > harmless because I am not changing their label config atm).

Yes, you're completely right! Now I see there is a bug in DM Core: when programmatically adding an assoc def to an existing type the assoc def might get no "Include in Label" setting, causing a NPE when trying to update the parent type's Label Config afterwards. I'll create a ticket and fix that bug in 4.8.6. For the meantime you could consider one of these workarounds: * Do the missing "Include in Label" settings manually in the Webclient. That works when you edit the assoc def directly (instead of the parent type). But to make your changes effective you have to restart the DM server afterwards (to update its type cache.) * Run a DB-fixing migration *before* your update-label-config migration. The fixing migration would directly fetch all assoc defs and store a "Include in Label" setting if no one exist. If you want I could provide you with the migration code. Please excuse the inconvenience. Thank you for reporting! Cheers, Jörg
