    <p>I am programming a Server Task Add-In and am trying to make a clean, recyclable code. I am looping through a set of databases, then through some documents within the database.</p> <pre><code> for (String serverAndFilename : listofServerFilenames) { String[] parts = serverAndFilename.split("!!"); currentGECDB = session.getDatabase(parts[0], parts[1]); if (currentGECDB.isOpen()) { collSourceDocuments = currentGECDB.search(this .getSearchFormula(this .getvariablePartOfSearchFormula())); countOfSearchDocuments = collSourceDocuments.getCount(); docToChange = collSourceDocuments .getFirstDocument(); while (docToChange != null) { if (changeNamesFieldsOnThisDocument(docToChange)) { // .... other code here } tmpdoc = collSourceDocuments.getNextDocument(); docToChange.recycle(); docToChange = tmpdoc; } } } } </code></pre> <p>I am concerned about the memory management issues with using a heavy Notes oject as a parameter to a Java function. Whilst checking the changes my function does, I am getting the 'old' values and need to make a recycle() on my document before re-retrieving the document.</p> <p>It seems to me that I am forced to only pass primitives as arguments to an external function i.e. </p> <pre><code>public booleanfunction (String ServerName, String ReplicaIDOfDatabase, String UNIDofDocument) </code></pre> <p>but that would imply many subsequent OpenDatabase calls, which are expensive. </p> <p>Is there a best way to do this?</p> <p>As an example, this is part of a JUnit Test I am making on the result:</p> <pre><code>public void testNewArrivalTaskExample() { try { testNewArrivalTask = GECTaskNewArrival.getTestTask(db, oli); testNewArrivalTask.save(); Document testdocNewArrival_1 = getNewTestSourceCourrierDocument(); for (NamesItemsInProcedure n : NamesItemsInProcedure.values()) { setNamesField(testdocNewArrival_1, n, GECTaskNewArrival.NEW_ARRIVAL_ROLE_MODEL, NamesItemsInProcedure.NOUVELLE_ARRIVEE); } testdocNewArrival_1.replaceItemValue("TestDocumentDescription", "NewArrival_AllFields"); testdocNewArrival_1.save(); GECTaskNewArrival gna = new GECTaskNewArrival(testNewArrivalTask, db, oli); gna.process(); Item itemsuivi = testdocNewArrival_1 .getFirstItem(NamesItemsInProcedure.SUIVI_COURRIER .getItemName()); System.out.println("Content of document without recycle + rebirth:"); printItemValuesToSysout(itemsuivi); System.out.println(NamesItemsInProcedure.SUIVI_COURRIER .getItemName() + " Should contain " + GECTaskNewArrival.NEW_ARRIVAL_NEWPERSON); String noteID = testdocNewArrival_1.getNoteID(); testdocNewArrival_1.recycle(); for (NamesItemsInProcedure n : NamesItemsInProcedure.values()) { boolean result = itemContainsThisForTestDoc(GECAlladin, noteID, n.getItemName(), GECTaskNewArrival.NEW_ARRIVAL_NEWPERSON); switch (n) { case ENCOURS_COURRIER: assertTrue(result); break; case AUTEURS_COURRIER: assertTrue(result); break; case SUIVI_COURRIER: assertTrue(result); break; case ECHEANCEMESSAGENOM_COURRIER: assertTrue(result); break; default: // assertFalse(result); break; } } } catch (NotesException e) { e.printStackTrace(); } } </code></pre> <p>and this is the console result:</p> <pre><code>Content of document without recycle + rebirth: Suivi has these values: Donald VieuxDeLaVieille/dsic/ville-ge` the item belongs to this document 929E` Suivi Should contain CN=Micky NouvelleArrivee/OU=salut/OU=Truc/O=Muche` Suivi has these values:` Donald VieuxDeLaVieille/dsic/ville-ge` CN=Micky NouvelleArrivee/OU=salut/OU=Truc/O=Muche` the item belongs to this document 929E` Suivi contains CN=Micky NouvelleArrivee/OU=salut/OU=Truc/O=Muche` </code></pre> <p>I am still stumped.</p>

    1. COI've seen no evidence of any problems passing NotesDocument objects to functions. I do it routinely. What do you mean by 'old' values?

    2. COI start with a Document. Item 'Status' has the value 'Start'. I then do some processing on the Document (changing the item to 'End'), make a save(). When I look into the document in the database using ScanEZ, the Status item has the value 'Start', as I am expecting, but in my code, when I do `item = doc.getfirstitem("Status"); String status = item.getItemValueString(), the answer is 'Start' and not 'End'. If I take the NoteID of the document, recycle it, the reload it with the noteID, then I get 'End'

    3. COPerhaps there's a typo above? If ScanEZ is saying the value is "Start", and getItemValueString() is giving you "Start", that seems like it's correct behavior. Or at least consistent behavior. Did you really mean to say that ScanEZ is saying the value is "End"? Can you replicate this in a small piece of agent code that you can post in its entirety?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
