Thanks for the tip. This was a big help.

The one modification I made was to have the closuure return a PagedResultList (same as the CriteriaBuilder.list() method). I was using the totalCount property in the controller to enable pagination on the UI so it was necessary.

Again, thanks a bunch.

Hi Justin, the above definitely worked for me.

Your stubbed version of the list method - is it definitely the list method of your domain object that the controller is accessing?

What I mean is, if it’s not the same signature and does not match the meta class method you’ve replaced, you will just get the real one being invoked.

Were you able to get this to work? When I tried something similar, I found that my stubbed version of the list call (Customer.metaClass.static.list = { Map params -> testItems }) was never invoked and instead the real one would be called.

I’m curious to know whether you got this to work.
