我创建了一个从文档开始的自定义工作流程，该工作流程旨在运行电子邮件脚本以向收件人发送指向共享文档的链接。用户可以将文件发送给多个人、组或两者。工作流在工作流启动后立即结束，这是使用计时器事件实现的（Activiti 会阻止您在没有任何任务的情况下启动和结束工作流）。
截屏
这适用于电子邮件模板（仅将其发送到 DOCUMENT_TEST 组，请参见下面的代码），但我有一些问题：
收件人
我需要将Select People和Select Group元素转换为mail.parameters.to_many方法的可用电子邮件地址。我了解要发送给显示的收件人，我会执行以下操作：
mail.parameters.to_many = ['ageorge', 'GROUP_DOCUMENT_TEST'];
我将如何遍历两个选择元素并编译可用的收件人数组？由于没有任务，我将如何在执行中获取这些数据？我最初认为它们是执行变量，但我的方法不起作用（参见 .bpmn 文件）。
邮件.执行（）
目前，我的邮件代码执行以下操作：
mail.execute(bpm_package.children[0].nodeRef);
这使用包中的第一个子节点，它恰好是附加的文档。我认为这是一个草率的工作，特别是因为 bpm_package 执行起来很慢（平均 10-20 秒）。如果我只想引用附加文档的节点，我会改用什么？（见配置自定义）
