if task.getPeriod() returns null, then 5.5 has not inserted that
Task into the working memory yet (while 6.0 will),<br>
so you need to do something like<br>
if (task.getPeriod() == null) {<br>
scoreDirector.beforeEntityAdded(task);<br>
scoreDirector.afterEntityAdded(task);<br>
}<br>
// and continue with <span>beforeVariableChanged (although you can
optimize this if-else stuff)<br>
