Good Morning, I have very simple problem migrating hibernate from version 3.0.5, all the queries with foreing keys throw the famous [BasicPropertyAccessor.get (167)], IllegalArgumentException occurred calling getter of XXXX.id, when I turn back to version 3.0.5 without making any changes works, if I change to 3.1.3 or 3.2, fails

I don't know if this is happening to anybody, if it is let me know and will post this to JIRA

I somebody has solved, I'll be glad to know the way to fix it

Thanks for help!

Hector

There were several queries in HSQL that functioned with versions before 3.1 where the where condition accept comparations between complex objects and primitive data types, this is not permited on recent versions

That was all the problem

Ej HQL

Before 3.1
from Product as product where product.type = :type
After 3.1
from Product as product where product.type.id = :type
