Cody Lerum commented on HSEARCH-937:
------------------------------------

Also all the entities load fine when they are queried via JPA/Hibernate Core (HQL, em.find(Company.class, 1L)) etc...

> I have run into an issue after moving from Search 3.1 to 3.4.1 and later to 4.0.Beta2.
> The issue is that when loading an result entity from a hibernate search query the load fails if the result entity has an associated entity where the id types are dissimilar.
> For example if I have Company with an id type of Long and employee with id type of Integer and I search and the result is the company entity my search throws the following stack trace.
> aused by: java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Integer
