Wasn't sure where you wanted this.
On your new version for 2.0, if you use the arrow to the right of the spawner entry to select the spawn, it looks like it is going to work, but when you find what you want, the spawner gump just disappears and nothing is entered into the line. It works if you type the item into the line manually.
yes, the fix is here.
