OR criteria Grails nested objects

Question

I'm trying to use createCriteria with OR on two nested objects.

This is the code I'm working with:

or {
  ordersSecondaryReceptionSystem {
    eq('code', params.receptionSystemCode)
  }
  ordersReceptionSystem {
    eq('code', params.receptionSystemCode)
  }
}

Only one of the two are being taken into account, the secondary one. Is there something I'm missing?

Answer 1

I was able to fix it by creating an Alias:

createAlias('ordersReceptionSystem', 'ordersReceptionSystem', Criteria.LEFT_JOIN)
                    createAlias('ordersSecondaryReceptionSystem', 'ordersSecondaryReceptionSystem', Criteria.LEFT_JOIN)
                    or {
                        eq('ordersReceptionSystem.code', params.receptionSystemCode)
                        eq('ordersSecondaryReceptionSystem.code', params.receptionSystemCode)
                    }
