Question

我有一个应用程序，如果填写所有目标字段（To：，cc：和bcc :)，但如果其中一个是空白，我收到一个错误，说明有一个无效的电子邮件地址。我使用的是文本输入字段，多个电子邮件地址由分号（;）分隔。如果输入字段为空，则不为该选项指定任何内容。知道为什么会这样吗？我使用什么值来setCcAddress和setBccAddresses函数什么都不显示。我尝试了几个（null，空列表）。

请参阅下面的代码。

public ID callersId;
private String transferUrl;

public String recipientEmail { get; set; }
public String ccEmail { get; set; }

public String bodyEmail { get; set; }
public String docName { get; set; }

    List<Contact> senderEmail = [SELECT Id, Email FROM Contact WHERE pse__Salesforce_User__c=:UserInfo.getUserId() LIMIT 1];
    bccEmail = senderEmail[0].Email;
    subjectEmail = 'Affiliate Consulting Engagement ' + affEngage.Name + ' - ' + affEngage.Engagement_Code__c;
    docName = affEngage.Name + '-' + affEngage.Engagement_Code__c;
