From what I’ve read this is a problem with getViewTypeCount. Im guessing that the method isn’t called when Im updating the adapter and calling adapter.notifyDataSetChanged();

The problem doesn’t occur if i set a new instance of the adapter as listAdapter.

How can I solve this problem? Can I force the activity to recall getViewTypeCount ?

    Correct. getViewTypeCount() is only called once.

    How can I solve this problem?

    Do not change the value of getViewTypeCount() for the lifetime of your adapter.

    Can I force the activity to recall getViewTypeCount ?

    Not that I am aware of, sorry.
