I have a detached parent object that contains a list of child objects. In my BackingBean, after retrieving the parent object (and the children), I add a new child to the collection. I now want to update the parent and have it save the new child object. I'm updating the parent object and the child collection is mapped as cascade save-update. I get an exception that it can't update because something is transient. Is it because I'm trying to save and update? I'm trying to update a parent and save a new item in the list of children. Is it possible to do what I describe? Is the solution to save the child item separately?

Thanks.
