Hi,
I occasionally get exceptions like this one here:

size of 0

My own code isn't really touched in this stack trace and I am wondering what
I might be doing wrong here?
I suspect it is something about the coordination of redraw/invalidation
events, but I don't know where to look exactly.
When I update the model (the sqlitedatabase) I run the following code on the
UI thread afterwards:
void refreshUI() {
((BaseAdapter) getListAdapter()).notifyDataSetChanged();
// the remaining calls are just included for completeness
// they update different ui elements, but don't access the cursor in
any way.
updateButtons();
updateControlPanelTitle();
updateProgressBar();
}
Any other information I can provide?
Cheers,
Mariano
