exception - OppRecordCombo : execution of BeforeUpdate caused by: System.FinalException: SObject row does not allow errors ()

Question

我在Opportunity对象上创建了一个触发器，用于在插入之前和更新之前，通过该触发器将Trigger.newMap变量作为自变量发送给我的顶点类，在其中我根据另一个Object中的记录检查特定组合的存在记录组合并尝试添加错误(如果不存在特定的记录模式)。但是，当我尝试创建或更新机会时，出现以下异常。

OppRecordCombo: execution of BeforeUpdate caused by: System.FinalException: SObject row does not allow errors () 

我的触发器在下面

trigger OppRecordCombo on Opportunity (before insert, before update) {
    if((Trigger.isBefore && Trigger.isInsert) || (Trigger.isBefore && Trigger.isUpdate)) {
        OppRecordComboClass opp = new OppRecordComboClass();
        opp.checkComboValidate(Trigger.newMap);
    }
}

我的顶点类如下

public without sharing class OppRecordComboClass {
    //private List<Opportunity> opportunities;
    String recordComboString;
    String oppComboString;
    List<String> recordComboStringList = new List<String>();

    public OppRecordComboClass() {
    }

    public void checkComboValidate(Map<Id, Opportunity> opportunities) {
        try {
            List<Record_Combination__c> recordcombo = [SELECT Client__r.Name,
                                                            Client_SFDC_ID__c,
                                                            Agency__r.Name,
                                                            Agency_SFDC_ID__c
                                                            FROM Record_Combination__c];

            for(Record_Combination__c recComb : recordcombo) {
                recordComboString = recComb.Client__r.Name + recComb.Client_SFDC_ID__c + recComb.Agency__r.Name + recComb.Agency_SFDC_ID__c;
                recordComboStringList.add(recordComboString);
            }

            List<Opportunity> oppCheckList = [SELECT Id,
                                                    Account.Name,
                                                    AccountId,
                                                    Agency_Name__r.Name,
                                                    Agency_Name__c,
                                                    Allow_New_Account_Combination__c
                                                    FROM Opportunity
                                                    WHERE Id in :opportunities.keySet()];

            for(Opportunity opp : oppCheckList) {
                if(opp.Allow_New_Account_Combination__c == false) {
                    oppComboString = opp.Account.Name + opp.AccountId + opp.Agency_Name__r.Name + opp.Agency_Name__c;
                    System.debug('This is the opp combo string akki ' + oppComboString);
                    if(!recordComboStringList.contains(oppComboString)) {
                        //Opportunity triggerOpp = opportunities.get(opp.Id);
                        opportunities.get(opp.Id).addError('This Customer and Agency combination doesn\'t exist in OB. Do you still want to create this Opportunity');
                    }
                }
            }
        } catch(Exception e) {
            System.debug('An exception occured at the line ' + e.getLineNumber() + ' exception is ' + e.getMessage());
        }
    }
}

谁能让我知道为什么会这样，如何解决？

不要将trigger.newMap传递给您的方法。这个变量是Map<Id, Opportunity>和when you are before insert ids don't exist yet(嗯，嗯)。您没有 map 键，因此变量将为空，并且逻辑将被跳过。改为传递trigger.new。

不要SELECT ... FROM Opportunity WHERE Id IN : ...。您从触发器那里传递了数据的"new"状态。如果您查询，将获得此保存操作之前的旧数据，而不是用户现在编辑的数据。还是什么都不是(因为如果您是before insert-资料在数据库中尚不存在)。处理原始的trigger.new。

您不能对查询的内容进行addError()。现在没有改变。 FinalException不是一个好名字，但是它告诉您将addError放在trigger.new的元素上
