NoMethodError in ScriptsController#edit

[esnible]

undefined method `name=' for nil:NilClass

To reproduce: Start Toaster. Go to http://:8080/scripts and click "Create new automation". Click "Add Parameter" then click "remove". Or click "save". Similar problem with an Ignored State Property or a State Property Watch.

What I was trying to do was use http://hummer.io/tmp/tomcat6-0.5.4.tgz as the cookbook instead of loading one from Opscode. The only way I was able to create an automation for that URL was with no parameters. When I click "edit" on that Automation and then try to add properties I get a similar error screen reading "undefined method `[]' for nil:NilClass"
