grails build an array with json builder

Question

I use this code to build an array of employees:

render(((new JsonBuilder())
        {
            'all' employees.collect { Employee employee ->
                [
                        id: employee.id,
                        name: employee.firstName + " " + employee.lastName
                ]
            }.sort() { it.name }
        }) as JSON)

the result is:

"{
    all: [
       {id: 1, name: "balh blah"},
       ...
    ]
}"

but I want a json of an array without the "all" field, like this:

"[
       {id: 1, name: "balh blah"},
       ...
 ]"

How can I achieve that?

Thanks for help!

Have you tried removing the 'all' part (line 3)?

You don't really need a JSonBuilder, if you have what you need in a collection, just return the collection as JSON.

def employee = Employee.findAll()
render employee as JSON

UPDATE: tried myself with the following code:

def  userList = User.list(params)
def all = userList.collect {User user ->
  [id: user.id,
  name : user.firstName + " " + user.lastName]
}.sort() { it.name }

render all as JSON
