Well, the docs are pretty clear that you can create a struct implicitly by
using struct dot notation... Ah but perhaps I need to be explicit about it
being a new struct each time. Wait... let's try this.
Ok. that is it. Now it works. I just added "<cfset fileInfo=strcutNew()>"
just inside the loop and it works as expected.
I wasearlier looking at a similar example I did a while back but couldn't
see the difference (assuming implicit creation was the same as explicit)
but in that case I used the full formal syntax for declaring and creating
structs including declaring a new struct.
So an easy fix. Thanks.
