我目前在 Eclipse Developer Studio 中使用 wso2 Business Process Server 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：
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……</p>
我正在使用 Developer Studio 3.2.0
这是我的 bpel 源代码：
