Hi Abhishek, I have placed the converView = null; as my first line in getView() method.
Now, the problem, that i mentioned earlier is not there (multiple checkboxes get selected when i select one checkbox in view). But, when i scroll the view up and down, i lose my selected checkbox (it get's unchecked). any thoughts?
