如何访问持久化实例的变量值? [英] How to access variable values of persisted instance?

问题描述

是否可以从持久实例中获取变量值?我有一个接受订单的工作流，并且有一个名为CustomerNumber的变量.订单初始化后，它等待订单批准.我想计算特定客户的等待工作流程. 我可以使用提升值或跟踪.如果在实例化工作流之前先构建它们，则此方法有效.在数百个工作流运行并持续存在之后，如果我决定访问另一个变量OrderDate，则跟踪和提升的价值将无法正常工作.

is it possible to get variable values from persistent instance? i have a workflow that accepts orders and have a variable called CustomerNumber. after order initialized it waits for order approve. i want to count waiting workflows for a specific customer. i can use promoted values or tracking. this methods work if i build them before i instantiate workflows. after hundreds of workflow run and persisted, if i decide to access another variable OrderDate tracking and promoted value will not work.

如果修改后的值不起作用，请尝试反序列化实例属性

If the pormoted value won't work,  try desserialize instance property
