Null Value Handling

While defining the attribute quality, the attribute ignoreNull allows controlling of how null values are to be treated.

If this value is set, the following result occurs:

  • If the new value is null, the old value is retained irrespective of weight
  • If the old value is null, the new value is retained irrespective of weight
Note: For multi value attributes, it is always going to be all or none. When applying the precedence, if the existing multivalue attribute has more weightage than the new MV attribute, the new value is ignored.
