by d_fdo＠yahoo.com
Hello guys ,
I am new to Seam .and I am suing richfaces I have the following .jsp:
<h:form>
| <a4j:commandLink value="Crear Area" action="#{areaAction.createArea}" style="float:right" />
| </h:form>
| <f:verbatim><br /><br /></f:verbatim>
| <h:outputText value="Listar Areas" />
| <rich:separator height="2" />
| <f:verbatim><br /><br /></f:verbatim>
| <h:form>
| <rich:dataTable id="miembroTable" value="#{areas}"
| var="a" rowKeyVar="index"
| onRowMouseOver="this.style.backgroundColor='#FFE4E1'"
| onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" >
|
| <h:column>
| <f:facet name="header">
| <h:outputText value="#"/>
| </f:facet>
| <h:outputText value="#{index+1}" />
| </h:column>
| <h:column>
| <f:facet name="header">
| <h:outputText value="Codigo"/>
| </f:facet>
| <h:outputText value="#{a.id}" />
| </h:column>
| <h:column>
| <f:facet name="header">
| <h:outputText value="Nombre"/>
| </f:facet>
| <h:outputText value="#{a.name}" />
| </h:column>
| <h:column>
| <f:facet name="header">
| <h:outputText value="Estado"/>
| </f:facet>
| <h:outputText value="#{a.status}" />
| </h:column>
| <h:column>
| <a4j:region>
| <a4j:commandButton immediate="true" value="Editar" action="#{areaAction.editArea}" />
| </a4j:region>
| </h:column>
| </rich:dataTable>
| </h:form>
and my backing bean:
@Name("areaAction")
| @Scope(ScopeType.CONVERSATION)
| public class AreaActionBean implements Serializable {
|
| @DataModel
| private List<Area> areas;
|
| @In(value="area", required=false)
| @Out(value="area", required=false)
| @DataModelSelection
| private Area selectedArea;
|
| @Begin(join=true)
| @Factory("areas")
| public void findAreaItems() {
|
| try {
| System.out.println("Retrieving Areas");
| areas = Area.getAll();
| } catch (Exception e) {
| System.out.println(e.getMessage());
| }
|
| }
|
| public String createArea() {
| selectedArea = new Area();
| return "crearItem";
| }
|
| public String editArea() {
| System.out.println(selectedArea.getName());
| //return "/Administracion/editArea.jsp";
| return "editarItem";
| }
|
| @End
| public String create() {
|
| try {
| selectedArea.createArea();
| FacesUtil.addInfoMessage("Area Creada Exitosamente");
|
| } catch (Exception e) {
|
| }
|
| return "success";
|
| }
|
| @End
| public String edit() {
|
| try {
| selectedArea.editArea();
| FacesUtil.addInfoMessage("Area Editada Exitosamente");
| } catch (Exception e) {
|
| }
|
| return "success";
| }
|
| }
If I click on the last row(edit button) , without having clicked another one before , I get an NullPointer Exception.....If I have clicked another row before (not the last row), it navigates to the edit page , but not with the last row element , but with the previously selected
This is the exceptionn I get

[JBoss Seam] - <s:selectItems> label and value
by monkeyden
I don't see a way to specify a different label and value when using <s:selectItems>. I see the value attribute ties in to the list of results. Functionally everything works fine. I would just prefer to use region.regionCode as the value and region.regionName as the label. Am I missing something? Thanks.
| <h:selectOneMenu id="regionSelect" value="#{contentAdmin.selectedRegion}" styleClass="formElement">
| <s:selectItems var="region" value="#{regions.resultList}" label="#{region.regionCode}"/>
| <f:converter converterId="entityConverter" />
| </h:selectOneMenu>
<framework:entity-query name="pages" ejbql="select p from Page p" order="pageCode"/>
| <framework:entity-query name="regions" ejbql="select r from Region r" order="regionCode"/>
| <component name="entityConverter"
| class="org.jboss.seam.ui.converter.EntityConverter">
| <property name="entityManager">#{entityManager}</property>
| </component>
