That's a good start :)

OK, I see what you mean. Well even so the coding would be/look much simpler.

Yes, I've been through them all but couldn't see that they would address

Will do.

I like this idea.

Is this regardless whether the lvFullRow object is set as item data or not?
(Don't think my English is correct there!)

I think it's important that whatever method is chosen, the
stringValueForNil option be included in one way or another.
