I have to handle a list with students who are either inscribben or matriculated. To model this I used @Inheritance. Now I want to show all of them in a Table, but with different attributes - depending on the subclass. My idea was mask the attributes with the rendered attribute in the JSF. Unfortunately I don't know how to do this. I already searched the internet, but I found now solution. Can somebody here help me?
The JSF: | <h:dataTable value="#{studentList}" var="stud" rendered="#{studentList.rowCount>0}" border="1"> | <h:column> | <f:facet name="header">Name</f:facet> | <s:link action="#{inscription.startEdit}" value="#{stud.givenName} #{stud.familyName}" /> | </h:column> | <h:column> | <f:facet name="header">Loeschen</f:facet> | <s:link action="#{inscription.delete}" value="loeschen" /> | </h:column> | <h:column> | <f:facet name="header">Prozent</f:facet> | <h:outputText value="#{stud.percentage}" /> | </h:column> | <h:column> | <f:facet name="header">Perzentil</f:facet> | <h:outputText value="#{stud.percentil}" /> | </h:column> | <h:column> | <f:facet name="header">Rang</f:facet> | <h:outputText value="#{stud.rank}" /> | </h:column> | <h:column> | <f:facet name="header">Durchschnitt</f:facet> | <h:outputText value="#{stud.mean}" /> | </h:column> | <h:column> | <f:facet name="header">Aequivalenz</f:facet> | <h:outputText value="#{stud.equivalence}" /> | </h:column> | </h:dataTable> | The accessed attributes (e.g. stud.mean) are from "inscribben" (that was the class I started with) ---^ The Session-Bean: | @Stateless | @Name("inscription") | public class InscriptionAction implements InscriptionFacade { | | @Logger private Log log; | @PersistenceContext EntityManager em; | @DataModel private List<Student> studentList;; | | @In(required=false) | @Out(required=false) | @DataModelSelection | private StudentInsc inscribben; | | @In(required=false) | @Out(required=false) | private Representative representative; | | @Factory("studentList") | public List<Student> getStudentList() { | studentList = (List<Student>) em.createQuery("from Student").getResultList(); | return studentList; | } | | public void setStudentList(List<Student> studentList) { | this.studentList = studentList; | } | .... | And the Entity Beans: | @Entity | @Inheritance(strategy = InheritanceType.SINGLE_TABLE) | public class Student implements Serializable { | | @Id @GeneratedValue | protected long id; | ..... | | @Entity | @Name("inscribben") | public class StudentInsc extends Student { | | @Length(max=30) private String kindergarten; | | @NotNull private boolean behavior; | @NotNull private boolean utilization; | @NotNull private boolean language; | @NotNull private boolean materials; | | @Range(min=0, max=50) private int percentage; | @Range(min=0, max=100) private int percentil; | @Range(min=0, max=6) private int rank; | @Range(min=0, max=20) private int mean; | @Length(max=15) private String equivalence; | .... | | @Entity | @Name("matriculated") | public class StudentMat extends Student { | .... | Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4123854#4123854 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4123854 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
