Hi all,
I've a situation where my business key is a combination of properties of two persistent entities. I am not sure how to use the "natural-id" element to group them. Following should be my business key
csaType + csaStartDate + csaEndDate + serialNumber (from Equipment.hbm.xml)
I appreciate your help. Thank you in advance!
