[JBoss Seam] - Injection of NULL immediately after outjection
by dkane
Hello
I have implemented a checkbox column for table multi-select, like in dvd store example.
When list is being updated (e.g.record is being removed), all checkboxes becomes unchecked with no depend on their previous state. I want checked positions to stay checked.
XHTML (action and checkbox are in bold):
|
| <a:outputPanel id="cartPanel" rendered="#{cartList.rowCount>0}">
| <div class="section">
| <h:form id="createOrder">
| <h1>Shopping cart</h1>
| <h:dataTable value="#{cartList}" var="item">
| <h:column>
| <f:facet name="header">Quantity</f:facet>
| <h:inputText value="#{item.quantity}" style="width: 30px;"/>
| </h:column>
| <h:column>
| <f:facet name="header">Name</f:facet>
| #{item.part.description}
| </h:column>
| <h:column>
| <s:link id="cancel" value="Remove" action="#{cart.removeSelectedPosition}" reRender="cartPanel"/>
| </h:column>
| <h:column>
| <h:selectBooleanCheckbox value="#{cartSelections[item]}"/>
| </h:column>
|
| </h:dataTable>
|
| <h:commandButton id="createOrderBtn" value="Create order" action="#{createOrder.createOrder}"/>
|
Shopping cart code (I have added some debug code for injection-outjection) :
| package com.avtohouse.ejb;
|
| import java.util.List;
| import java.util.ArrayList;
| import java.util.Map;
| import java.util.HashMap;
| import javax.ejb.Remove;
|
| import org.jboss.seam.ScopeType;
| import org.jboss.seam.annotations.*;
| import org.jboss.seam.ScopeType;
| import java.io.Serializable;
| import org.jboss.seam.annotations.datamodel.DataModel;
| import org.jboss.seam.annotations.datamodel.DataModelSelection;
| import org.jboss.seam.annotations.security.Restrict;
|
| import javax.ejb.Stateful;
|
|
| @Stateful
| @Name("cart")
| @Scope(ScopeType.SESSION)
| @Restrict("#{identity.loggedIn}")
|
| public class ShoppingCartBean implements ShoppingCart, Serializable
| {
| private List<OrderCMP> cartOrderList = new ArrayList<OrderCMP>();
|
| @DataModelSelection
| private OrderCMP selectedPosition;
|
| @In
| UserCMP user;
|
| private Map<OrderCMP, Boolean> cartSelections;
|
| public ShoppingCartBean()
| {
| cartSelections=new HashMap<OrderCMP, Boolean>();
| }
|
|
| @In(required=false)
| public void setCartSelections(Map selection)
| {
| System.out.print("Injected selection = "+selection);
| if (selection==null) return ;
| cartSelections=selection ;
| }
|
| @Out(required=false)
| public Map getCartSelections()
| {
| if (cartSelections==null) cartSelections=new HashMap<OrderCMP, boolean>();
| System.out.print("Outjected selection = "+cartSelections);
| return cartSelections;
| }
|
| public void addPart(PartCMP part, int quantity)
| {
| for (OrderCMP order: cartOrderList)
| {
| if (order.getPart().getPartId()==part.getPartId())
| {
| order.addQuantity(quantity);
| return;
| }
| }
| OrderCMP newOrder= new OrderCMP();
| newOrder.setUserId(user.getUserId());
| newOrder.setPart(part);
| newOrder.setQuantity(quantity);
| cartOrderList.add(newOrder);
| }
|
| public void addPart(PartCMP part)
| {
| this.addPart(part,1);
| }
|
| public void removeSelectedPosition()
| {
| if (selectedPosition!=null) removePart(selectedPosition);
| }
|
| public void removePart(OrderCMP order)
| {
| cartOrderList.remove(order);
| }
|
| @DataModel
| public List<OrderCMP> getCartList()
| {
| return(cartOrderList);
| }
| ............
|
After clicking "Remove" (removePart method is being called), position is properly removed but log says :
15:20:07,640 INFO [STDOUT] Injected selection = {}
15:20:07,640 INFO [STDOUT] Outjected selection = {}
15:20:07,640 INFO [STDOUT] Injected selection = null
So the problem is that cartSelections becomes null somehow.
Will appreciate any hints how to solve this .
Thanks !

Hi all
I have a web app which is deployed on Tomcat 5 which I'm trying to deploy to JBoss 4.2.0 without much luck. It's a war file unpacked so all it contains is a series of jsp pages and the following:

I have a server.xml file in my Tomcat directory which I have not copied over - is this required? Also, I'm connecting to a mysql database so I have copied the mysql-ds.xml file into the deploy folder but I've not configured the file yet to point to the right datasource as the app isn't deploying. Any help would be appreciated!
