Grails List Restful Resources return Unexpected results

I'm trying to build a restful api with grails. Now for resource listing I got a weird response:

{
   "empty": false,
   "totalCount": 229
}

But if I try to show a specific resource i.e /resource/1 I got expected response. What is going wrong with this?

It seems indeed that the origin of the problem is related to the version of Grails. I do not know if you found a solution in the meanwhile, but I just stumbled upon this problem and found this bug report: https://jira.grails.org/browse/GRAILS-11892

A workaround consists in appending toArray() to all lists of objects. If you are using RestfulController an example for the index method (supposing you want to return a list of objects) could be:

class BookController extends RestfulController {
    static responseFormats = ['json', 'xml']
    BookController() {
        super(Book)
    }

    @Override
    def index(Integer max) {
        params.max = Math.min(max ?: 10, 100)
        respond listAllResources(params).toArray(), formats: ['json', 'xml']
    }
}

This will give you the expected result rather than the ou7tput you cite in your question.
