Unable to save a domain class instance from Groovy Console in GGTS

Question

I am creating a Grails project using Groovy/Grails Tool Suite. If I choose Run As >> Groovy Console , I can create sample objects from my domain classes but cannot save them.

So,

new things.Thing(height: 20, length: 30)

creates a new Thing, but

new things.Thing(height: 20, length: 30).save()

throws an exception

No signature of method: thing.Thing.save() is applicable for argument types: () values: []

even though respondsTo states that Things respond to save().

Does anyone know why this is happening?

That's the Groovy console, not the Grails console. They use the same code and look the same, but the Grails version hooks into the application, whereas the Groovy console just has access to the code. To run the console, go to Grails Tools | Open Grails Command Prompt and enter console in the text field.

This is just a GUI wrapper for running grails console from the commandline.
