We have an entity that inherits from another entity as described in the code
snippet below. The specific field we are having trouble with is the
editorInfo field.
editorInfo needs to be optional because, as you would expect, a new entity
has not been modified, so it has no editor information.
The specific problem is that intermittently the editorInfo field will not be
filled out even though the appropriate rows exist in the joined table. At
times the join works perfectly, then, for the same entity and keys, it will
apparently fail and the value of editorInfo will be NULL.
Has anyone else seen this kind of issue? Is there something wrong with the
way we have annotated the relationship?
Thanks!
