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)
