Well...
i've tried simplyfing the channelId, but that didn't solve the problem
So we migrated to version 1.5.0.
As a result we now do not get the "application key is null..." exception,
but instead we get another exception when creating the channel:

However running gwt-gae-channel sample project works.
One difference we have noticed is that our token looks different than the
gwt-gae-channel sample project token.
Example of our token: channel--j5okj1-test
gwt-gae-channel token: channel-j5okj1-test
As you see our token has one hyphen more.
Any ideas?
Thanks,
Z
