Xpages & get result from agent

HCL Domino Domino Forum
1

Hi,

I have a list with documents and when I open document, I need to get some information about the document using the code written in LS. I wrote scenario:

  1. create temp doc and save

  2. call agent(temp.getNoteID)

  3. getDocumentByID(temp.NoteID) and use results

It works only if after step 2. I re-open page and I execute step 3 on page load.

Unfortunately this is not an option because I need quick operation and use partial-refresh. With this scenario at step 3. I do not have results of the agent execution. It does not work also if I split step 3 when sub-page is loaded.

I tried to call ‘delete’ on the document but it does not help.

What I would like the most would be scenario written on the top of the post in single server call but I need any solution that will give me results of LS execution without reloading whole page.

Thanks in advance,

Grzegorz

Subject: workaround - i hope temporary

when I click button, I call web agent and wait for result as json - i have return value from agent. this is client JavaScript.

when i have result i am searching for another button and call click method.

  • this is where my agent execution is complete and I have result values. I do not need temporary document for return value.

this second button executes my Server Side code…

I have not compared it with server side only execution but I belive that it will be slower due to additional server roundtrip.

Subject: workaround - final and nice

reopen database with code below and getDocumentByID will give you fresh document.

session.getDbDirectory(“”).openDatabase(database.getFilePath());

Subject: Could you give more informations ?

reopen database with code below and getDocumentByID will give you fresh document.

session.getDbDirectory(“”).openDatabase(database.getFilePath());

compared to the code shown above, where is this line?

I have the same problem, in

getComponent(“Numero2”).setValue( document1.getItemValueString(“Numero”));

document1.getItemValueString(“Numero”)

dont retrieve backend document field data…

Subject: the code

place button on xpage and place this code in event handler.

// create and save temporary document (can be existing, depends on you)

var a:NotesAgent = database.getAgent(‘returnSomething’);

var doc:NotesDocument = database.createDocument();

doc.replaceItemValue(“Form”,“testAgent”);

doc.save();

// get note id

var noteId:String = doc.getNoteID();

// run agent. the agent takes ParameterNoteID, set some fiels and save document

a.runOnServer(noteId);

// the same document - not possible to get values from agent execution…

var docret = database.getDocumentByID(noteId);

getComponent(‘inputText1’).setValue( docret.getItemValueString(‘somevalue’));

agent returnSomething

Sub Initialize

Dim s As New NotesSession

Dim agent As NotesAgent

Set agent = s.CurrentAgent



'get document created by xpage

noteId$ = agent.ParameterDocID	

Dim doc As notesdocument

Set doc = s.CurrentDatabase.GetDocumentByID(noteId$)



' set value and save

Call doc.ReplaceItemValue("somevalue","hello")

Call doc.Save(True, False)

End Sub

Subject: UPDATE | This is not a bug

After investigation by the team is was concluded that this is not related to XPages but to the Backend classes. Also this is not a bug as the backend maintains a list of opened document and returns the same document instance from the same session, until the document is actually discarded. A call to recycle() should be done before calling the agent in order to get ot properly working
