Replicate: after clicking on a search item, the corresponding item appears on the right. Click on the item's title, and the item disappears.
Why does this happen: when you click on the item's title, it actually causes the dialog to perform a "selectGear" call; it searches for the gear-id (which doesn't exist), causing the null item to be added.
To fix: when clicking on the title, do not trigger selectGear.
