Hi

Please find the Image here : http://ramsateesh.googlepages.com/index.html

I have a persistant object of the parent and I have my mapping file which allows hibernate to create the parentId (primary key). But I have a list of child objects embedded in the parent object which have parentId as their foreign Key. I have cascade all in my parent.hbm.xml file.

When I am doing session.save(parent), I am getting an exception saying that I am trying to insert data into child with parentId value eq null.

I tried to debug the code by removing cascade all from the parent mapping file. Right after a successful save of parent I thought it would update the parentId in the children but it didn't and I think that's the reason why it's failing to insert data when cascade all option was present in the parent mapping file.

Can someone help me solving this problem, what do I have to do so that when I save my parent my child records also get saved.[/img]

Hi,

It's a little odd that you have both parentId and parent Object in the Child. You should need only the Object really.

Anyway is your parentId in the child set? is it a required field i.e nullable=false? From the ER diagram it looks like its required. If it's required you need to explicitly set it before saving the parent (which will cascade to the child)
