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
