控制器逻辑：

def updateObject() {

    Object o = Object.get(params.id as Long)

    o.otherObjects.clear()

    objectDataService.saveObject(o.id)

    OtherObject newObject = new OtherObject;

    o.addToOtherObjects(newObject)

    objectDataService.saveObject(o.id)

}

服务逻辑

def saveObject(long profileId) {
    o.save(flush:true)
}

怎么了

在90％的情况下，这将正常工作。

问题
