From the 14.3 release notes:
- Fixed: Filtering the messages displayed in the email grid in webmail by doing a search or applying a view filter and then selecting all messages and performing an action on them now correctly operates on the list of displayed messages and not all messages in the folder.
Need to apply this same fix to Contacts section. Search for contacts named Robert, Select All to mark those contacts, Delete, and poof -- ALL your contacts are gone!
It's time to update Contacts so it works in 3 panes like email messages:
Then maybe you could use the same or similar code for both sections.
