AXAPTA - Post invent journal which it's form open

If you want to post a record like this, AX will not let you post, with an error about record is using by another. This code part I learned from Volkan Şişman lets to post:

InventJournalCheckPost      journalCheckPost;
JournalForm                 journalForm;
;
...
journalForm      = JournalForm::fromArgs(args);
journalCheckPost = InventJournalCheckPost::newFromForm(args,journalForm);
journalForm.runbaseMainStart();
journalCheckPost.run();
journalForm.runbaseMainEnd(journalCheckPost,false);

AXAPTA post invent journal

    journalTableData        journalTabledata;
    inventJournalTable      inventJournalTable;
    InventJournalCheckPost  journalCheckPost;
    ;
    inventJournalTable = inventJournalTable::find(Line.InventJournalId);
    // Posting Journal
    journalTableData = JournalTableData::newTable(inventJournalTable);
    journalTableData.updateBlock(JournalBlockLevel::InUse,JournalBlockLevel::None);
    if (infolog.num(Exception::Error))
        return;
    infolog.clear(0);
    journalCheckPost =
    InventjournalCheckPost::newJournalCheckPost(JournalCheckPostType::Post,InventJournalTable);
    journalCheckPost.parmAutoBlock(true);
    journalCheckPost.run();

    if(journalTableData.hasErrors())
        return;
