WSO2 业务流程 bpel，GUI 中带有“if”组件的错误

我目前正在使用 Eclipse Developer Studio 中的 wso2 Bu​​siness Process Server 开发一个简单的业务流程。我创建了一个带有“if”条件的小 bpel 流程。我让它在服务器上正常工作，没有任何问题。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。当我点击“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？如果能够为每个 GUI 配置“if”条件以进行演示，那就太好了……

我使用的是开发者工作室 3.2.0

这是我的 bpel 源代码：

正如所解释的那样，这是一个已知问题WSO2 开发人员工作室编辑分配活动的属性 https://stackoverflow.com/questions/17547806/wso2-developer-studio-edit-properties-of-an-assign-activity

请尝试一下开发工作室3.0.0 http://wso2.com/more-downloads/developer-studio/3.0.0， 这样可行！
