Question

in few places in my code I query db using def results = Domain.findAllBySomething and I expect an array (i use results.size() to determine how many results I have).
However, if findAll call results in a single object returned, it will not be returned as array but a reference to this single object.

Is there any way I could force grails to always return array, no matter how many results there are?

I’m using 2.1.

findAll* is supposed to always return a Collection – I tried the following code in 2.1:

def person = Person.findAllByName('kelly')
println person.size()
println person.class
println person[0].name

prints

1
class java.util.ArrayList
kelly

Can you add some code that shows it returning a single instance?
