I have a class called DrugDay, which has a boolean called valid.

In my WHEN block,

$drugDayA : DrugDay($uniqueIdA : uniqueId, $ctCodeA : ctCode, $dayA : day, valid == true)

having the condition, "valid == true", breaks the UI, with no error in the logs. The guided rule has to be deleted, and created again. It is happy without the "valid == true" condition.

Is this a reserved variable name?
