Property not found on type org.hibernate.collection.Persist

[jdijkmeijer]

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
java 1.5.
jboss 4.2.2GA
seam 2.0.0.GA
icefaces 1.6.1

is "competence" a @Name("competence") on the Competence class or?

[nickarls]

nevermind, saw it on the datatable now...

JSF doesn't support dataTable backed by Sets (Seam does if you use @DataModel). Use something like http://jroller.com/page/pmuir?entry=using_sets_in_jsf

Hi I'm currently trying to implement

<function-name>asList</function-name>
<function-class>
functions.AsList
</function-class>
<function-signature>
java.util.List asList(java.util.Collection)
</function-signature>


but I'm a bit mistified where to put it. From Google I have the impression its in taglab.xml, but I'm not sure where to put with icefaces.
Thanks again.
Jeroen
