Changeset 163 for Dev/trunk/classes/pipelineSequencer.php

Timestamp:

11/18/11 15:28:51 (13 years ago)

Author:

Message:

• Basically alles gefixt om te werken met een local copy van de session, opgeslagen in $_SESSIONlocalSessionCopy?.
• Flag $_SESSIONupdateNeeded? toegevoegd om aan te geven wanneer er een update uit de database nodig is in plaats van gewoon verder werken met de local copy.
• '123'/'456' placeholder routine weggehaald uit returnStep.php
• CreateObject? doet nog niets, maar dat komt volgende week! (AJAX-aangestuurd object creation, met als doel: pipeline editing zonder constante page refreshes).

File:

• Dev/trunk/classes/pipelineSequencer.php (modified) (3 diffs)
