Thanks for the reply. Well, entry is an instance of a separate class:
@Embeddable
public class JournalEntry {
@org.hibernate.annotations.Parent
private GoalToAchieve goalToAchieve;
@Column(length = 255, nullable = false)
private String entry;
@Temporal(TemporalType.TIMESTAMP)
@Column(nullable = false, updatable = false)
private Date insertDate = new Date();
...plus the getters and setters
This being a value type embeddable component, it is represented with a
table with only a foreign key to the parent entity it belongs to:
goalToAchieve_id
So, if I pass the entry String as a parameter (I am not sure if it
would be convenient to have a a few sentences as url params), how can
I turn it into a reference to the object I want to actually remove
from the collection?
Thanks again
