hmm sadly removing the loadWith and LoadOnDemand and putting the menuInit in ADDON_LOADED doesn't work either, now the context menu doesn't show up at all, although that worked before.
And even with this approach the hook for the "Summon Random Favorit Mount"-button gets called only when i manually press it in the MountCollection tab and not if i drag it on my hotbars :/
is it possible the dragged button becomes a spell and thats why it doesn't call the hook anymore ?
any other ideas ? appreciate your help, though
i mean last resort would be to auto-create a macro with just "/run C_MountJournal.SummonById(0)", because that works, and see if my addon can replace the "Summon Random Favorit Mount"-button in the hotbars with it. (or notify the user to replace the actionbar spell manually, but i would prefer if it just works out of the box)
