Groovy console for Grails does not work

Steps to demonstrate the problem:

• Create a new Grails project: untitled
• Create a new Grails domain class: Widget
• Give it one class attribute: name
• Run Grails command: `generate-all Widget`
• Debug the application
• Notice that you can create, list, and delete Widgets (i.e., the default H2 database and GORM are working)
• Use Tools, Groovy Console...
• Change the class path to untitled_main
• Type `def ws=Widget.findAll()`
• Notice that it automatically adds `import untitled.Widget` to the top of the console listing
• Run the script

Get the error: "java.lang.IllegalStateException: Either class [untitled.Widget] is not a domain class or Form has not been initialized correctly or has already been shutdown."

What needs to happen to make the console work with a Grails application (and GORM)?
