Thanks for letting me know. Alright, so: This is the parent class:
@Entity public class GoalToAchieve { @Id @GeneratedValue private Long id; @org.hibernate.annotations.CollectionOfElements @JoinTable (name="GoalToAchieve_entry", joincolum...@joincolumn(name="goalToAchieve_id")) private Set<JournalEntry> entries = new HashSet<JournalEntry>(); public Set<JournalEntry> getEntries() { return entries; } public void setEntries(SortedSet<JournalEntry> entries) { this.entries = entries; } public void addEntry(JournalEntry newEntry){ entries.add(newEntry); } public void deleteEntry(JournalEntry entry){ entries.remove(entry); } ..plus some other standard fields with getters and setters This is the child-class: @Embeddable public class JournalEntry { @org.hibernate.annotations.Parent private GoalToAchieve goalToAchieve; @Column private Long mark; public Long getMark() { return mark; } public void setMark(long mark){ this.mark = mark; } @Column(length = 255, nullable = false) private String entry; @Temporal(TemporalType.TIMESTAMP) @Column(nullable = false, updatable = false) private Date insertDate = new Date(); ..plus the rest getters and setters And this this the jsp part where I display the collection: <s:if test="goalToAchieve.entries.size > 0"> <display:table name="goalToAchieve.entries" requestURI="" uid="thisGoal"> <display:column property="entry" /> <display:column property="date" sortable="true" defaultorder="ascending" title="TimeStamp"/> <display:column property="mark" /> <display:column> <a href="<s:url action='UpdateEntryForm'> <s:param name="name" value="%{goalToAchieve.owner.fullName}" /> <s:param name="mark" value="#mark" /> </s:url> ">Edit</a> </display:column> <display:column> <a href="<s:url action='DeleteEntryForm' var="entry" escapeAmp="false"> <s:param name="name" value="%{goalToAchieve.owner.fullName}" /> <s:param name="id" value="%{goalToAchieve.id}" /> <s:param name="mark" value="entry.mark" /> <s:property value="%{entry}"/> </s:url> ">Remove</a> </display:column> </display:table> </s:if> ..and the delete action, which should take an entry reference and remove it from the collections looks like this: public class DeleteEntry extends ActionSupport{ public String execute(){ goalToAchieve.deleteEntry(entry); return SUCCESS; } private JournalEntry entry; private GoalToAchieve goalToAchieve; private long id; ... + getters and setters I guess right now, my problem has become how to pass a parameter referring to en entry (the mark field) to the delete action. Next, I would do a lookup within the action to find the entry object and remove it from the parent object collection, by calling deleteEntry(JournalEntry entry) On Mon, Jul 13, 2009 at 9:16 AM, Greg Lindholm<greg.lindh...@gmail.com> wrote: > You are not providing enough information for anyone to help you.
