There appears to be two types of Autocomplete:
1) The one used in the search where more than one username can be selected and submit is required
2) The one used in the find members search where a one name is selected and is auto-submitted
The first type always puts in a comma and a space after you select a username. Is there an option to remove this comma and space? The reason I ask is that in my add-on only one username is allowed.
I know I could use the second type, but that automatically runs the code once a name is selected, I don't want this behavior as I would like the user to have to press the Submit button.
