[jboss-user] [JBoss Seam] - @DataModelSelection Is Update When @Factory Method Gets Call

[elvisisking]

I'm writing a very simple Web application and trying to use POJOs instead of SBs. I have a page that displays a parent object and it's children. The children's names are displayed in the cells of a datatable. Each child has an associated SEAM link that is used to redisplay the current page but now using the child as the parent. When I click the child link the page does redisplay but since the @DataModelSelection value is always set to the first child in the collection the wrong child is displayed (unless I click on the first child:-). I've verified that the @DataModelSelection is only updated when the @Factory method is called. See code (modified for simplicity) below. Thanks much for your help. 

xhtml code:

                        <rich:dataTable
                            value="#{pojo.kids}"
                            var="child">

                            <rich:column>
                                <f:facet name="header">
                                    <h:outputText
                                        styleClass="tableHeaderText"
                                        value="Child Name" />
                                </f:facet>
                                <s:link
                                    action="#{pojo.viewChild}"
                                    value="#{child.name}">
                                </s:link>
                            </rich:column>
                        </rich:dataTable>

pojo code:

@Name( "pojo" )
@Scope( ScopeType.SESSION )
public class Pojo implements Serializable {

    @Out
    @DataModelSelection( "kids" )
    private Node child;

    private Node node;

    @DataModel
    private List kids;

    @Factory( "kids" )
    public List getNodeChildren() throws Exception {
	this.kids = this.node.getChildren();
        return this.kids;
    }

    public String viewChild() throws Exception {
        this.node = this.child;
        return "view";
    }
}
