So with the recent discovery of the RefreshingView, I have decided I wanted
to transplant all my code from ListView.
Unfortuantely, I am getting a nasty error and i have tracked the actual
failure to the 'getItemModels()' abstracted function. I retrieve the
appropriate iterator, and debug shows that it is being returned to the
original class/function that calls it. What I am doing is using an Iterator
from another POJO backend class. The code itself is quite similar to the
code I had for listView with the addition of retrieving the iterator for
getItemModels().
I am not sure if thats the actual code thats causing the problem. The code
is below the error message.
Anyway, yeah let me know what you guys think.
