NullPointerException error in grails
I'm really getting mad with this.
My goal is to save in which state/region an object is, so I set up this domain class:
class State {
String stateName
String stateIsoCode
static hasMany = [regions: Region]
static constraints = {
stateIsoCode unique:true
stateName unique:true
}
}
class Region {
String regionName
String regionIsoCode
static belongsTo = [state: State]
static hasMany = [provinces: Province]
static constraints = {
regionIsoCode unique:true
regionName unique:true
}
}
when someone want to insert the location of his object he can do it with a select which have as value the isoCode of the state or region
so in the controller I try to set the location of the object in this way:
materialInstance.state = State.findByStateIsoCode(params?.state)
materialInstance.region = Region.findByRegionIsoCodeAndState(params.region,materialInstance.state)
And I get this error:

I can't understand what causes it, overmore if I comment the peice of code which save the state and the region, I go through the controller (and I get the error because they are not nullable field) and then I uncomment it , it works.
I am using grails whit a nosql database and I am working on the debug enviroment
Thank you
