  I was able to reproduce this error by doing the following on a fresh install of ubuntu-jeos 8.04.1:

  sudo adduser --home /home/disco --shell /bin/bash disco sudo usermod -a -G admin disco su disco

  sudo apt-get install openssh-server openssh-client lighttpd erlang python python-setuptools python-dev git-core wget gcc build-essential

  cd ~ git clone git://github.com/tuulos/disco.git disco

  wget http://pypi.python.org/packages/... tar -xvf python-cjson-1.0.5.tar.gz cd python-cjson-1.0.5/ sudo python setup.py install cd .. sudo rm -rf python-cjson-1.0.5 rm -rf python-cjson-1.0.5.tar.gz

  wget http://discoproject.org/disco-0.... tar -xvf disco-0.1.1.tar.gz rm -rf ../../disco-0.1.1.tar.gz

  ssh-keygen -N '' -f ~/.ssh/id_dsa cat ~/.ssh/id_dsa.pub >> ~/.ssh/authorized_keys

  cd disco/conf

  sudo ln -s /etc/init.d/sshd /etc/rc2.d/S98sshd

  //change the master port to be enabled //start the master //start the node //hit the master ip:7000 and add "localhost" to the table and "1" to the workers" //click "save table

  I had the same problem with a fresh installation, the field name was wrong on config.js. This patch is a possible fix:

  Attila,

  I think that your patch doesn't fix it.

  ".setting" with a dot is jquery's way of referring to all elements of the class "setting".

  Thanks for the idea anyways. I've had trouble repeating this bug but I'm working on it..

  You are right, that's even a different settings. After adding some debug to the Erlang and Javascript part I figured out what's happening. You need to enter the value in the field and press enter before sending it. Without the enter javascript happily sends an empty string. save_config_table: [[<<>>,<<"4">>]] save_config_table: [[<<"ec2-67-202-53-140.compute-1.amazonaws.com">>,<<"4">>]]
