Exception when creating dummy server

[Glenn Arndt]

When I try to create a dummy server (with any name), I get the error below. BuildMaster does succeed in creating the dummy server, but it has no name. I then can edit the details of the no-name dummy server and give it a name, and it takes the name just fine.

When you say dummy server, you mean the "Dummy Agent" in the Dummy extension? Very likely could be a bug in that extension; we primarily use that to test extensibility points. I assume this is for testing multi-server functionality and the like?

But in any case, I don't think the Dummy Agent will provide any useful functionality; you probably want to create additional Local agents. This can only be done via the API / Database directly.

Just look at how server ID=1 is configured, and add as many additional servers as you'd like (just make sure to use different names).

[Glenn Arndt]

Yes, it's from the Dummy extension. When I click the "Add Server" button on the Servers page, it lets me choose an agent type -- self-hosted, IIS-hosted, SSH-based, or Dummy Agent.

I was hoping to use dummy servers as stand-ins for real servers that don't (yet) exist so I could create my deployment plan before the servers exist. Then, once they exist, I would just point the deployment steps to the real servers.
