I've searched online including this forum, but I'm not able to find the answer to this.

I have a listview. Once selected, there's a showTextDialog that occurs. However, when you click cancel, I don't want anything to be selected... I tried changing the selectionIndex to 0 but that didn't work.

Current behavior: when you click cancel, it still highlights the item you clicked on initially

How do I unselect the element?

the listview component is limited, you might want to use a Spinner instead, see also https://groups.google.com/d/msg/mitappinventortest/elurVKDJL9o/t9OQt8l5CgAJ

You can't just add a prompting element at slot 1 of the selection list,
like "Pick a card"  and use index 1 for the not-selected option?

Thank you Taifun. It's a bit interesting. From the AI website:

SelectionIndex
The index of the currently selected item, starting at 1. If no item is selected, the value will be 0. If an attempt is made to set this to a number less than 1 or greater than the number of items in the ListView, SelectionIndex will be set to 0, and Selection will be set to the empty text.

Is this a bug or am I misintrepreting the above statement?

If I wanted to request this as a feature, where would I submit that?

I got this to work...

You set the elements back to the listview and this clears the selection:

Nice and simple.
