Address Book link doesn't define _source
|Reported by:||adrianw||Owned by:|
Clicking the Address Book link at the top of the page fails to set the "_source" value. This means that attempting to change address books with the the "Groups" column fails with the following:
this.env.address_sources[this.env.source] is undefined
Manually entering the link for the second address book works, as does subsequent clicks in the "Groups" column. Links copied from the "Groups" column includes the _source value in the URL.
