Can't use DomainClass.get(id)

def act=Account.get(user.actId) // user.actId=3
Here is the error msg:

I'd say that your user object is null. Try to log the value before you use it with Account.get() in your controller or service like this:

if(log.debugEnabled) {
   log.debug "User account ID: '${user.actId}'"
}

I am sure user.actId is not null.

Does your Account class sit in the grails-app/domain directory?

[tomLee]

Yes,it's in domain directory, I have tried delete this class, and run the following script:

grails creaet-domain-class Account
grails generate-all Account

Found the reason,it's because of the relationship between my domains is wrong.
