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);
