WSO2 业务流程 bpel，带有“if"的 gui 错误零件 [英] WSO2 Business Process bpel, error in gui with "if" component

问题描述

我目前在 Eclipse Developer Studio 中使用 wso2 业务流程服务器处理一个简单的业务流程.我创建了一个带有if"条件的小 bpel 进程.我让它在服务器上工作没有问题.但是，我必须在源代码中设置if"条件，我无法为每个 gui 配置 if 组件.当我单击if"组件的详细信息"选项卡时，总是出现以下错误:

I currently work on a simple business process with the wso2 Business Process Server in Eclipse Developer Studio. I have created a little bpel process with an "if" condition. I got it to work on the server without problems. But, I had to make my "if" condition in the source code, I was not able to configure the if component per gui. I always get the following error when I click on the "Details" tab of the "if" component:

An error has occurred. See error log for more details.
org.eclipse.ui.internal.EditorReference.<init>(Lorg/eclipse/ui/internal/EditorManager;Lorg/eclipse/ui/IEditorInput;Lorg/eclipse/ui/internal/registry/EditorDescriptor;)V

有谁知道如何避免这个错误?为演示配置每个 GUI 的if"条件会很棒……

Does anyone know how to avoid this error? It would be great to configure the "if" condition per GUI for demonstrations…

我正在使用 Developer Studio 3.2.0

这是我的 bpel 源代码:

推荐答案

这是一个已知问题，已解释 WSO2 开发者工作室编辑分配活动的属性

It's a known issue as explained WSO2 developer studio edit properties of an assign activity

请试用 Developer Studio 3.0.0，这样可以！
