NotesXSPDocument with Agent runWithDocumentContext

when i try to pass an NotesXSPDocument to an agent with runWithDocumentContext to manipulate some fields, i never get the new values to the frontend fields. I have tried a fullrefresh and a partialrefresh. When i just print the field value i get the changes successfully.

Here is an example of the XPage

<?xml version="1.0" encoding="UTF-8"?>
<xp:view xmlns:xp="http://www.ibm.com/xsp/core">

    <xp:panel id="thePanel">
        <xp:this.data>
            <xp:dominoDocument var="document" formName="from"></xp:dominoDocument>
        </xp:this.data>
        <xp:button value="Label" id="button1">
            <xp:eventHandler event="onclick" submit="true"
                refreshMode="partial" refreshId="thePanel">
                <xp:this.action><![CDATA[#{javascript:
var agent = database.getAgent("test");
agent.runWithDocumentContext( document.getDocument());
print( "Value-->" +  document.getDocument().getItemValueString("InMemReturn"));}]]>
                </xp:this.action>
            </xp:eventHandler>
        </xp:button>

        <xp:br></xp:br>
        <xp:br></xp:br>
        <xp:inputText id="inputText1" value="#{document.InMemReturn}"></xp:inputText>
    </xp:panel>

</xp:view>

here is the Agent

Option Public
Option Declare


Sub Initialize

 Dim session As New NotesSession
 Dim doc As NotesDocument

 Set doc = session.Documentcontext
 doc.Appenditemvalue "InMemReturn", CStr(Now)

End Sub

Have I missed something?

Manipulating documents in agents that bound to input fields are tricky. The XPages runtime isn't really aware what the agent is doing. Quite often you are actually better off converting an agent into a Java bean and call that one. It gives you the opportunity to clean up code and optimize performance. It also removes the performance penalty of loading the agent runtime for an operation. "I want to reuse existing code" is often overrated here...

But you asked... so here we go. The documentation suggest you can use

agent.runWithDocumentContext(document.getDocument(true));

to ensure backend changes are applied. Try that and let us know how it went. I actually would take a slightly different approach and bind the input field to a view variable and write that one only back on the save event. Something like:

 <xp:inputText id="inputText1" value="#{viewScope.InMemReturn}"></xp:inputText>

and in your SSJS:

     var agent = database.getAgent("test");
     var doc = document.getDocument(true);
     agent.runWithDocumentContext(doc);
     viewScope.InMemReturn = doc.getItemValueString("InMemReturn");

and in a querySave event:

     document.getDocument().replaceItemValue("InMemReturn",viewScope.InMemReturn);

Let us know how it goes.

You dont save the document in the Agent 

     Call Doc.save(false,true,false)
