Grails cannot save object

Question

Im getting a rather strange error trying to save objects to my database. The code has worked perfeclty when trying to save the base class objects but now I am trying to save a domain class that inherits from the base domain class.

Here is the parent class:

package com.twc.fatcaone

class Record {

long batchID

}

and the child class that I am trying to save:

package com.twc.fatcaone

class AccountRecord extends Record {

    long uniqueId
    String accountId
    String type
    String insurance
    String currencyType
    float amount
    String upSerDel
    String generalComments

    static mapping = {
        collection "accountRecords"
        database "twcdb"
}
}

The code in my service that's trying to do the save:

accountRecordList.each { 

                def accountRecord = new AccountRecord(batchID: params.selectedBatch.id,
                                                        uniqueId: it.uniqueId,
                                                        accountId: it.accountId,
                                                        type: it.type,
                                                        insurance: it.insurance,
                                                        currencyType: it.currencyType,
                                                        amount: it.amount,
                                                        upSerDel: it.upSerDel,
                                                        generalComments: it.generalComments)

                       if (!AccountRecord.save(flush: true, failOnError: true)) {
                           println "ERROR: Record could not be saved!"
                           def errorValue = AccountRecord.errors
                           println errorValue
                       }

and the error I get when trying to do the save:

难道不是在调用save函数之前在AccountRecord一词中使用小写的“ a”吗？
