Grails - gorm false OR NULL

Question

I have a field in a table called disabled that is a Boolean. I'm trying to query for both false or null but can't seem to get it to work. I have tried a few things, most likely solution but didn't seem to work is

p = book.createCriteria().list {
'in'('createdUnderAccountCustomerNumber', accountIds)
and {
   'in'('createdUnderProfessionalCustomerNumber', professionalCustomerNums)
   isNull('disabled')
   or {
     eq('disabled', false)
   }
}

Basically I want get all the books created under a list of accounts and a list of professionals which has disabled set to either false or null

Answer 1

Put the two parts of the or inside the closure:

or {
    isNull('disabled')
    eq('disabled', false)
}
