From f194f323f4c0ae98dfb8fc9e558516d92e132ada Mon Sep 17 00:00:00 2001 From: Bruno Windels Date: Thu, 13 Sep 2018 18:43:24 +0200 Subject: [PATCH] postpone loading the members until the user joined the room when peeking, the members weren't being loaded at all because the room wasn't available yet, and the need for loading the members was never re-evaluated after that. This only loads the members once the user has joined the room, which also helps to avoid load all the members before an invite is accepted. --- src/components/structures/RoomView.js | 28 +++++++----- src/components/views/rooms/MemberList.js | 56 ++++++++++++++++-------- 2 files changed, 56 insertions(+), 28 deletions(-) diff --git a/src/components/structures/RoomView.js b/src/components/structures/RoomView.js index 88c1d153eb..3a2a80f06a 100644 --- a/src/components/structures/RoomView.js +++ b/src/components/structures/RoomView.js @@ -314,16 +314,6 @@ module.exports = React.createClass({ // Stop peeking because we have joined this room previously MatrixClientPeg.get().stopPeeking();
