I am having one scenario which i am unable to do so...Need you expertise to help me

1. RMB click on a row
- A context menu appears and this one I am able to handle since spy is able to identify and able to add to the repository.
2. There is one item (e.g. Fruits) on the above context menu which needs to be selected
- This one also I am able to handle since spy is able to identify and able to add to the repository.
3. There is another context menu when we click on the Fruits and its a scrollable list in which I need to select one.
- The element from this context menu is able identified by spy but when i am trying to add to the repository the message i get is "The item is no longer valid"
