Update of title/name of channel

[OsteHovel]

I have a issue with updating the title, I can get the BeamChannel using

 Futures.addCallback(beam.use(ChannelsService.class).findOne(beamUser.channel.id), new ResponseHandler<BeamChannel>() {

but how do i update the title/name and push it back again?
Ive tried to change the name by:

beamChannel.name = "Maybe API is working?";
Futures.addCallback(beam.use(ChannelsService.class).update(beamChannel), new ResponseHandler<BeamChannel>() {

I get this error:

Thank you, i'll take a look at this soon.

[OsteHovel]

Bump?

I know this is old, but the first thing I noticed is the stream key is null. This is the first I've seen this API but I don't think I should assume utilizing the username and password automatically implicate the stream key was used.

I have the same problem. Probably a usage error. How are we supposed to update channel information with the java api?
