BuddyPress: BBP_BuddyPress_Activity::register_activity_actions() not running early enough

[r-a-y]

Synopsis

BuddyPress 1.6 introduced the "Activity" dashboard to edit activity stream items.

When editing a bbPress forum activity item, the activity type changes from 'bbp_reply_create' / 'bbp_topic_create' to something else.

This creates this problem:
​https://buddypress.trac.wordpress.org/ticket/4786

Why?

bbPress is not registering its activity actions early enough.

The BBP_BuddyPress_Activity class runs on bp_init at priority 10:
​https://bbpress.trac.wordpress.org/browser/tags/2.2.3/includes/extend/buddypress/loader.php#L137

While in that same class, it tries to register its activity actions:
​https://bbpress.trac.wordpress.org/browser/tags/2.2.3/includes/extend/buddypress/activity.php#L132

The 'bp_register_activity_actions' hook runs at bp_init at priority 8 so it's a chicken-before-egg scenario.

Proposed solution

Move the setup_components() hook to run at priority 7:

// Setup the components
add_action( 'bp_init', array( $this, 'setup_components' ), 7 );

In the attached patch, I've also registered some additional activity actions for the groups component.

Not sure what the consequences are with moving the hook a little earlier, but this was the easiest fix I could find.

Are the additional activity stream actions really necessary? Won't that fragment the activity stream actions?

(In [4719]) Whitespace cleanup in BuddyPress activity.php. See #2176.

(In [4720]) In BuddyPress's loader, setup components in priority 7, to get them in before activity actions are registered. Props r-a-y. Fixes #2176.

Hi JJJ,

Didn't get an email about this!

Re:

It isn't necessary for this ticket, but it might be better to add them anyway since bbP adds its own activity entries into the groups component. I'll leave it to your discretion.
