Actualmente trabajo en un proceso de negocios simple con el servidor de procesos de negocios wso2 en Eclipse Developer Studio. He creado un pequeño proceso bpel con una condición "if". Lo tengo para trabajar en el servidor sin problemas. Pero tuve que hacer mi condición "si" en el código fuente, no pude configurar el componente if por gui. Siempre obtengo el siguiente error cuando hago clic en la pestaña "Detalles" del componente "si":

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

¿Alguien sabe como evitar este error? Sería genial configurar la condición "if" por GUI para demostraciones ...

Estoy usando Developer Studio 3.2.0

Aquí está mi código fuente de bpel:
