GORM strangeness

Grails version 2.3.8


Вот такая конструкция не работает

runners = Runner.methodReturningDetachedCriteria(params).findAll {
    lastName =~ "%${lastName}%"
}

Такая тоже

def filter = {
    lastName =~ "%${lastName}%"
} as DetachedCriteria<Runner>
runners = Runner.methodReturningDetachedCriteria(params).findAll(filter)

А такая вполне себе работает

def filter = {
    lastName =~ "%${lastName}%"
} as DetachedCriteria<Runner>
runners = Runner.methodReturningDetachedCriteria(params).where(filter).findAll()
