检索Java代理对文档所做的更改

我从Lotus Script向Java代理传递参数,如下所示:

Set db = session.CurrentDatabase    
Set doc = db.CreateDocument     
Set uiDoc = workspace.CurrentDocument

Call doc.AppendItemValue("fileName", "SomeString" )
Call doc.Save(True, False)

Set MyAgent = db.GetAgent("AgentName")
Call MyAgent.Run(doc.NoteID)    
Set session = New NotesSession
Set db = session.CurrentDatabase

result = doc.GetItemValue("Result")(0)

代理在Java中说:

Session session = getSession();
AgentContext agentContext = session.getAgentContext();
Agent agent = agentContext.getCurrentAgent();
Database db = agentContext.getCurrentDatabase();
Document doc = db.getDocumentByID(agent.getParameterDocID());
String fileName = doc.getItemValueString("fileName");
doc.appendItemValue("Result","MyResult");
doc.save();

这位特工做得很好。我检查了参数文档,它确实包含代理的结果。但是,我的表单无法读取Result参数。
