Parent Class reference field on Entity class recordIssue The Parent class lookup on Entity class record is not displaying all the entity classes available. It is displaying only entity classes which is associated with the primary entity class (The primary entity class here as the “is root” if true for it) Once a class is selected then when looked up again all classes are shown.CauseDesigned behavior.ResolutionWhen the value is selected for the first time, the below is returned based on parent class field which is checking child.addQuery('roll_up_to', "CONTAINS", root); (comes from GRCUtilsBase Script include's _getProfileClassesRollingUpToRoot)It is the expected behavior when user want to select parent class for first time , we show only those classes which are rolling up to root class. Once user selects a class which rolls up to root then it is allowed to select any class in the system That way we are ensuring that all the classes in the system are rolling up to root in some way
