WSO2 BPS 3.2人工任务分配给多人创建流程处于失败状态 [英] WSO2 BPS 3.2 human task assignment to multiple people creating Process in failed status

问题描述

我正在尝试创建 wso2 人工任务，其中必须由多个所有者以某种顺序给予批准.我正在从异步 BPEL 流程中调用人工任务.我能够成功上传流程和任务包.但是当我尝试创建流程实例时，我在日志中遇到以下错误:

I am trying to create wso2 human task where the approval has to be given by multiple owners in some sequence. I am calling human task from Asynchronous BPEL process. I am able to upload the Process and task packages successfully. But when I try to create the process instance, i am getting below error in the logs:

在Task中设置工作流的代码片段如下.

Code snippet for setting the workflow in Task is given below.

`<htd:peopleAssignments><htd:potentialOwners><htd:sequence type="all"><htd:来自logicalPeopleGroup="shippingLine"><htd:argument name="role">shippingLineRole</htd:参数></htd:来自><htd:来自logicalPeopleGroup="cho"><htd:argument name="role">角色</htd:参数></htd:来自></htd:序列></htd:potentialOwners>

`<htd:peopleAssignments> <htd:potentialOwners> <htd:sequence type="all"> <htd:from logicalPeopleGroup="shippingLine"> <htd:argument name="role"> shippingLineRole </htd:argument> </htd:from> <htd:from logicalPeopleGroup="cho"> <htd:argument name="role"> choRole </htd:argument> </htd:from> </htd:sequence> </htd:potentialOwners>

`

知道这里出了什么问题.当工作流只有一个所有者时，任务创建工作正常.

Any idea what is going wrong here. As the task creation is working fine when workflow has single owner.

推荐答案

您为多个用户分配的人员错误.从 BPS 3.1.0 WSO2 BPS 开始支持基于表达式和文字的用户分配.如果您需要多个用户分配，您需要使用基于表达式或基于文字的用户分配.有关正确语法，请参阅人工任务规范 [1].

Your people assignment is wrong for multiple users. From BPS 3.1.0 WSO2 BPS supports Expression and literal based user assignment. If you need multiple user assignments you need to use either expression based or literal based user assignment. See humantask spec [1] for correct syntax.
