[JBoss Seam] - Re: @RaiseEvent possible bug
by ilya78
Ok, here is a bean and page that reproduces the problem:
Bean:
| @Stateful
| @Scope(ScopeType.CONVERSATION)
| @Name("raiseProblem")
| public class RaiseProblemAction implements RaiseProblem {
| @In FacesMessages facesMessages;
|
| @Remove @Destroy
| public void destroy() {
|
| }
|
| @Begin
| public void startConv() {
| facesMessages.add("Conversation started");
| }
|
| @End
| public void endConv() {
| facesMessages.add("Conversation ended");
| }
|
| @RaiseEvent("someEvent")
| public void raiseAnEvent() {
| facesMessages.add("Event raised");
| //Events.instance().raiseEvent("someEvent");
| }
|
| @Observer(value="someEvent")
| public void observerMethod() {
| facesMessages.add("Event observed");
| }
|
| }
|
I start the conversation from the main menu by calling:
| <s:link action="#{raiseProblem.startConv}" value="Raise Problem Conversation">
| </s:link>
|
Clicking on the above link works fine and displays raiseProblem.xhtml:
| <!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:rich="http://richfaces.ajax4jsf.org/rich"
| xmlns:a="https://ajax4jsf.dev.java.net/ajax"
| template="layout/template.xhtml">
|
| <ui:define name="body">
|
| <h:messages globalOnly="true" styleClass="message"/>
|
| <s:link action="#{raiseProblem.raiseAnEvent}" value="Raise Event"/>
|
| </ui:define>
|
| </ui:composition>
|
However when I click the 'Raise Event' link, it throws a NullPointerException in observerMethod(), because facesMessages is null (not injected properly).

If instead of @RaiseEvent("someEvent") I use Events.instance().raiseEvent("someEvent"), everything works fine.

[JBoss Seam] - Radio button select list to create data in foreign table
by david.spark
I'm sure this must be fairly trivial but I can't seem to get it to work (too late in the day I think :) ). I want to link the value of a radio button set to a value in a foreign table. The problem I seem to be having is that initially there is no value set so there is no corresponding row in the table. I want completing the radio button (then clicking on a save button) to create the row in the table.
My page code is thus:
<h:column>
| <f:facet name="header">Performance</f:facet>
| <h:selectOneRadio value="#{staffBooking.staffFeedback.rating}">
| <f:selectItem itemValue="4" itemLabel="Excellent"/>
| <f:selectItem itemValue="3" itemLabel="Good"/>
| <f:selectItem itemValue="2" itemLabel="Average"/>
| <f:selectItem itemValue="1" itemLabel="Bad"/>
| </h:selectOneRadio>
| </h:column>
and my entity bean code is:
@Entity
| @Table(name = "`Staff Bookings`")
| public class StaffBooking implements Serializable
| {
|
| ...
|
| @OneToMany(mappedBy="staffBooking")
| private List<StaffFeedback> staffFeedback = new ArrayList<StaffFeedback>();
|
| ...
|
| public List<StaffFeedback> getStaffFeedback()
| {
| return staffFeedback;
| }
and
@Entity
| @Table(name = "tblStaffFeedbackRating")
| public class StaffFeedback implements Serializable
| {
|
| ...
|
| @ManyToOne
| @JoinColumn(name="StaffBookingsUID")
| private StaffBooking staffBooking;
|
| ...
|
| public Byte getRating()
| {
| return rating;
| }
but when I try to view the page I get:
