I've recreated this with a simple example using Seam Gen. If you have a PERSON entity and a CITY entity. Then you wish to show a list of CITYs with a column holding a ui:repeat (or similar) displaying all associated PERSONs. The cause of the problem is that this is an "all-in-one" type page where the form to add the record is on the same page as the table to display. I suspect that something is needed to force the refresh.
The page: | <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" | "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";> | | <ui:composition xmlns="http://www.w3.org/1999/xhtml"; | xmlns:s="http://jboss.com/products/seam/taglib"; | xmlns:ui="http://java.sun.com/jsf/facelets"; | xmlns:f="http://java.sun.com/jsf/core"; | xmlns:h="http://java.sun.com/jsf/html"; | xmlns:a="https://ajax4jsf.dev.java.net/ajax"; | xmlns:rich="http://richfaces.ajax4jsf.org/rich"; | template="layout/template.xhtml"> | <ui:define name="body"> | <h:messages globalOnly="true" styleClass="message" id="globalMessages"/> | <h:form id="person" styleClass="edit"> | <rich:panel> | <f:facet name="header">Create Person</f:facet> | <s:decorate id="firstnameDecoration" template="layout/edit.xhtml"> | <ui:define name="label">Firstname</ui:define> | <h:inputText id="firstname" value="#{personHome.instance.firstname}"/> | </s:decorate> | <s:decorate id="surnameDecoration" template="layout/edit.xhtml"> | <ui:define name="label">Surname</ui:define> | <h:inputText id="surname" value="#{personHome.instance.surname}"/> | </s:decorate> | <s:decorate id="cityDecoration" template="layout/edit.xhtml"> | <ui:define name="label">City</ui:define> | <h:selectOneMenu id="city" value="#{personHome.instance.city}" style="width:250px;"> | <s:selectItems value="#{cityList.resultList}" var="city" | noSelectionLabel="Please Select..." label="#{city.cityname}"/> | <s:convertEntity /> | </h:selectOneMenu> | </s:decorate> | <div style="clear:both"> | <span class="required">*</span> | required fields | </div> | </rich:panel> | <div class="actionButtons"> | <h:commandButton id="save" value="Save" | action="#{personHome.persist}" rendered="#{!personHome.managed}"/> | </div> | </h:form> | <rich:dataTable var="city" value="#{cityList.resultList}" | rowClasses="rvgRowOne,rvgRowTwo" id="cityTable"> | <h:column> | <f:facet name="header">City</f:facet> | #{city.cityname} | </h:column> | <h:column> | <f:facet name="header">people</f:facet> | <ui:repeat var="person" value="#{city.persons}"> | <h:outputText value="#{person.firstname} #{person.surname}"/> | <br/> | </ui:repeat> | </h:column> | </rich:dataTable> | </ui:define> | </ui:composition> | The page has no pages.xml entries or associated page.xml file. The persist action returns to the current page. I would have thought that as the dataTable is re-rendered, that the List of Persons would be refreshed; however it isn't. And I have changed the PersonHome object from what Seam generated to remove the PersonHome from the conversation so that the same page can be reused: | package com.seamtest; | | import org.jboss.seam.annotations.In; | import org.jboss.seam.annotations.Name; | import org.jboss.seam.annotations.Transactional; | import org.jboss.seam.contexts.Contexts; | import org.jboss.seam.framework.EntityHome; | | @Name("personHome") | public class PersonHome extends EntityHome<Person> { | | public void setPersonPersonid(Long id) { | setId(id); | } | | public Long getPersonPersonid() { | return (Long) getId(); | } | | @Override | protected Person createInstance() { | Person person = new Person(); | return person; | } | | public Person getDefinedInstance() { | return isIdDefined() ? getInstance() : null; | } | | @Override | @Transactional | public String persist() { | String status = super.persist(); | Contexts.removeFromAllContexts("personHome"); | return status; | } | | } | The Person entity is unchanged from Seam-Gen. It contains only firstname, surname and City. I have changed the City entity to store a java.util.List of Persons rather than a set: | package com.seamtest; | // Generated Apr 16, 2007 6:03:07 PM by Hibernate Tools 3.2.0.b9 | | import java.util.ArrayList; | import java.util.List; | | import javax.persistence.CascadeType; | import javax.persistence.Column; | import javax.persistence.Entity; | import javax.persistence.FetchType; | import javax.persistence.Id; | import javax.persistence.JoinColumn; | import javax.persistence.ManyToOne; | import javax.persistence.OneToMany; | import javax.persistence.Table; | | import org.hibernate.validator.NotNull; | | /** | * City generated by hbm2java | */ | @Entity | @Table(name = "CITY", catalog = "SEAMTEST") | public class City implements java.io.Serializable { | | private long cityid; | private String cityname; | // private Set<Person> persons = new HashSet<Person>(0); | private List<Person> persons = new ArrayList<Person>(0); | | public City() { | } | | public City(long cityid) { | this.cityid = cityid; | } | public City(long cityid, String cityname, | List<Person> persons) { | this.cityid = cityid; | this.cityname = cityname; | this.persons = persons; | } | | @Id | @Column(name = "CITYID", unique = true, nullable = false) | @NotNull | public long getCityid() { | return this.cityid; | } | | public void setCityid(long cityid) { | this.cityid = cityid; | } | | @Column(name = "CITYNAME") | public String getCityname() { | return this.cityname; | } | | public void setCityname(String cityname) { | this.cityname = cityname; | } | @OneToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY, mappedBy = "city") | public List<Person> getPersons() { | return this.persons; | } | | public void setPersons(List<Person> persons) { | this.persons = persons; | } | | } | | Happy to email a stripped down project if it would help.
