Hi,
I have a datamodel of objects(keywords) having a one - many relation with
other objects (competences).
Keyword.java:
| @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy
= "keyword")
| public Set<Competence> getCompetences() {
| return this.competences;
| }
|
| public void setCompetences(Set<Competence> competences) {
| this.competences = competences;
| }
|
Competence.java:
| @ManyToOne(fetch = FetchType.LAZY)
| @JoinColumn(name = "keyword_id", nullable = false)
| @NotNull
| public Keyword getKeyword() {
| return this.keyword;
| }
|
| public void setKeyword(Keyword keyword) {
| this.keyword = keyword;
| }
| @ManyToOne(fetch = FetchType.LAZY)
| @JoinColumn(name = "person_id", nullable = false)
| @NotNull
| public Person getPerson() {
| return this.person;
| }
| public void setPerson(Person person) {
| this.person = person;
| }
|
|
Once the user selects a Keyword, the chosen keyword becomes the keyword in
focus via:
| @DataModel(value="keywords")
| private List<Keyword> keywords;
|
| @Out(required=false)
| @DataModelSelection(value="keywords")
| Keyword focusKeyWord;
|
And the user is taken to a new page, On the new page I want to show the
competences attached to the focusKeyWord:
| <ice:dataTable var="competence" value="#{focusKeyWord.competences}"
id="test">
| <ice:column>
| <f:facet name="header"><ice:outputText value="naam"/></f:facet>
| <ice:commandLink value="#{competence.person.firstname}"
action="{personMgr.selectPerson}">
| <f:param value="#{competence.person.personId}" />
| </ice:commandLink>
| </ice:column>
| </ice:dataTable>
|
But this fails with the exception: Property 'person' not found on type
org.hibernate.collection.PersistentSet. Should I use a second datamodel for the
competences attached to my focusKeyWord or are there smarter ways to solve this
exception?
Many thanks in advance!
PS my environment:
Mac Ox 10.4.11
