Lately we've been fetching messages only after entering the MUC, so that
we already have occupants to attach to them (due to `fetchMembers` being
called before) and thereby avoid rerenders.
I've now moved message fetching into the `initialize` method and added
missing event handlers for attaching/removing the occupant from a
message as it comes online or goes offline.
We still avoid (some) rerenders because we fetch and wait for cached
occupants before fetching cached messages and we wait for `fetchMembers`
before triggering `enteredNewRoom` which causes MAM messages to be
fetched.
in which you can set user affiliations and roles.
Also, let getAffiliationList return an Error instead of `null` if you're
not allowed to fetch a particular affiliation list.
Don't remove affiliation for occupants if we weren't allowed to
fetch that particular affiliation list.
Previously, if fetching the list failed, we would return an empty array,
which would imply that the affiliation list is empty and that all
users with the given affiliation should have their affiliations removed.
Instead we now return `null` and properly account for that when setting
affiliations on existing contacts based on the returned member lists.
* Explicit forwards and backwards paging
* Include upper or lower bound when calling `RSM.prototype.next` or `RSM.prototype.previous`
* Bugfix: Don't override new RSM parameters (caused infinite recursion)
If we've fetched the roster before within this session, then we don't
have to do so again, regardless of whether versioning is supported or
not, otherwise, even if we have a cached roster, we still need to get
the latest one again.
triggering connectionInitialized.
That way, when listening for `connectionInitialized`, we'll know when it
fires whether we've attached to a BOSH connection or not.
