工作流程批准任务 [英] Workflow approval task
问题描述
我在将工作流部署到新的pwa实例时遇到了问题。我创建了一个PSWApprovalTask。批准后，"状态"列将设置为"已批准"。这是不正确的，状态应该是'已完成'，并且工作流程结果'已批准'。
示例提案似乎可以很好地设置任务，我的代码可以在开发服务器上运行。我只是没有看到错误的专栏是如何获得批准的结果。工作流程永远不会进入下一阶段。
Hi, I am running into a problem when deploying my workflow to a new instance of pwa. I create a PSWApprovalTask. When i approve it, the 'Status' column is set to 'Approved'. This is incorrect, the Status should be 'Completed', and the Workflow Outcome 'Approved'. Sample proposal seems to set up tasks fine, and my code works on a development server. I just don't see how, the wrong column is acquiring the result of an approval. The workflow never advances to the next stage ..

更多信息当我单击"批准"或"拒绝"时，在批准任务上，日志报告，
A little more info, when I click 'Approve', or 'Reject', on Approval task the log reports,

这是奇数，因为在样本提案工作流程批准期间没有抛出此类错误。
which is odd, because no such error is thrown during Sample Proposal workflow approvals.
