[Anthill-pro] Is this a feature, a bug, or user error?

[I'm resending my reply to this since it apparently got rejected due to
the attachment. I've moved the attachment to here
<http://home.comcast.net/~pwsteele/deploy.jpg> . The original message
follows:]
The agent filter is set to "Scripted", pointing to the "All Agents From
List" script I wrote, and the Agent Quantity field is set to -1. A user
can select any number of agents out of the chosen environment on any
given run of the deploy workflow. I've attached a sample launch screen.
In this example, the user has selected "Rack 5" as the environment and
further filtered the list of servers to populate to just three servers.
The Rack 5 environment has over 20 servers in it. The problem is that
the deploy script fails to pick any agents if even one of the agents in
the selected environment is offline. In this example for instance the
user has selected systems 2, 3, and 4. However, if some system other
than these three was offline for some reason, the deploy script fails
with Anthill reporting "Not all agents in server group Rack 5 were
online."
I've tested my script, and on input the agents array contains the list
of currently online agents from the chosen environment, just as I'd
assume. On output, the filtered list correctly contains the subset of
agents the user specifies via the input field "agentNames". The job
still fails to run if any of the full set of agents is offline. This
will be a very likely scenario, especially with the large number of test
servers we have. Is there a solution to this problem?

Peter,
Is the user always selecting 5 agents and is the job going to run on
each of those agents? On the agent filter of the job, what do you have
the Agent Quantity set to?
