Question

以下是我的两个域类

class Line_Of_Business { static hasMany = [lp：Lob_Position_Type_Mapping]

String LOB_NAME;
String ACTIVE_FG;
String LOB_USER_CREATED;
Date   LOB_DT_CREATED;
String LOB_USER_MODIFIED;
Date   LOB_DT_MODIFIED;

//tells grails the PK
static mapping = {      
    version false
    columns { id column:'LOB_ID' }
    id generator:'sequence', params:[sequence:'LOB_ID_SN']
}   

static constraints = { 
    LOB_NAME(nullable:false,blank:false,maxSize:100)
    ACTIVE_FG(nullable:true,blank:false,maxSize:1)
    LOB_USER_CREATED(nullable:true,blank:true)
    LOB_DT_CREATED(nullable:true,blank:true)
    LOB_USER_MODIFIED(nullable:true,blank:false)
    LOB_DT_MODIFIED(nullable:true,blank:false)
}

}

import java.util.Date;

class Lob_Position_Type_Mapping {

Integer LOB_ID;
Integer CUST_POSITION_TYPES_ID;
String LPM_USER_CREATED;
Date   LPM_DT_CREATED;
String LPM_USER_MODIFIED;
Date   LPM_DT_MODIFIED;

static mapping = {
    version false
    columns { id column:'LPM_ID' }
    id generator:'sequence', params:[sequence:'LPM_ID_SN']
}

static constraints = {
}

}

LOB列表正在顺利进行。当我点击每个LOB到达异常

我是grails的新手。有人可以检查一下，让我知道我做错了什么。
