Hi,
I have some problems with property-refs and composite-ids. It's rather hard to explain, but I'll give it a shot :)
I have some class A with a composite-id and another object B with a many-to-one relationship to A. The table in the database where object B is persisted into, has a foreign key to a column of the table where objects of A are persisted into. That column is a property of A but not the primary key (= a composite-id).
Now, when initializing the context I'll get an ArrayOutOfBoundsException. When I remove the many-to-one tags with the property-refs from the mapping files, everything is fine.
I spent a lot of time in debugging the app but at some point (just before the exception) the debugger shows me the following information for the ArrayHelper.slice method:
strings=String[1] [0]="myclassA_.myPropertyInAForTheForeignKey"
begin=0
length=2
length=2 is a problem since my strings array has only length=1
so... what i guess is (didn't find the time yet to check the source code).... when using property-refs, Hibernate is initializing the lenght parameter to the number of properties in the primary key of object A.
Is this true? Has anyone had the same probem
