Hey, there seems to be an issue with you organize your model internal pointers, to quote the documentation, an internal pointer must identify the parent of the corresponding item. In your code you organized it that the internalPointer() references the item itself. This is an intentional choice within the library as it has as consequences:

  • there cannot be an inconsistency between row and internalPointer() --- otherwise there would be a redundancy
  • a user can organize internal pointers so that they are needed only for intermediate nodes (with at least one child)
  • the views can adjust indexes in one go (and not half before and half after the change)
