BuddyPress.org

I just found that the https links in the activity action do not work. Here is a normal activity action ( the text before each activity update content ):
[use name] posted an update in the group [group name] 2 minutes ago

[use name] links to the user’s profile
[group name] links to the group page.

The two links are not https consistent, whenever I use https to post the updates or to view the updates. I suppose it should have https at the beginning of the link if I use https, and http at the beginning if using http.

To fix this, shall I hook to the filter bp_get_activity_action? Any suggestions?
