How do I retrieve a record with two fields for PK

[Frank]

Hello,

I have this defined:
DataContext context = DataContext.getThreadDataContext();     
Bsypemp emp = null;
emp = (Bsypemp) DataObjectUtils.objectForPK(context, Bsypemp.class, id);
my problem is that the PK consists of two fields EMHSP# & EMEMP

What is the correct syntax for getting a record?

Thanks

Frank
