No I'm not "whacking" the child views lol. I'm actually using the remove(Object o) method to remove a row. I am however using View.GONE to hide a child view but that I know is not really deleting the view. Anyway, I achieved what I was after by going at it using a different method. I still don't know why accessing the tag of the view would give me a class cast exception when I know I set it to an Integer inside the getView(...) method.
