Hi, I’m facing a problem that the group channel collection handler not trigger properly when user does not have any joined channels before.

Steps:

  1. initialJoinedChannels is empty
  2. user join a channel
  3. onChannelsAdded not trigger (Unexpected)
  4. refresh page
  5. initialJoinedChannels has one channel one (expected)
  6. user join another channel
  7. onChannelsAdded trigger properly (expected)
const groupChannelFilter = new GroupChannelFilter();
groupChannelFilter.includeEmpty = true;

const collection = sb.groupChannel.createGroupChannelCollection({
  filter: groupChannelFilter,
  order: GroupChannelListOrder.LATEST_LAST_MESSAGE,
  limit: PAGE_SIZE,
});

collection.setGroupChannelCollectionHandler({
  onChannelsAdded: (c, channels) => {
    console.info("On channels added", c.source);
  },
  onChannelsUpdated: (c, channels) => {
    console.info("On channels updated", c.source);
  },
  onChannelsDeleted: (c, channelIds) => {
    console.info("On channels delted", c.source);
  },
});


const initialJoinedChannels = await collection.loadMore();
