dynamic panel group not re-rendered

[faupel]

Hi,

I want to create a dynamic panel group each time a value in a combo box is selected, but the getter is not called when the component is re-rendered. I know that it works with the value attribute of an output text. Is there a way to re-render a value binding? Thank you in advance.

<rich:panel>
    <h:form id="dynamicPanelGroupForm">
        <h:selectOneMenu>
            <f:selectItem itemValue="1" itemLabel="one" />
            <f:selectItem itemValue="2" itemLabel="two" />
            <a4j:support event="onchange" actionListener="#{dynamicPanelGroupBean.refreshPanelGroup()}" reRender="panelGroup" />
        </h:selectOneMenu>
     <h:panelGroup id="panelGroup" binding="#{dynamicPanelGroupBean.panelGroup}" />
    </h:form>
</rich:panel>

@AutoCreate
@Scope(ScopeType.EVENT)
@Name("dynamicPanelGroupBean")
public class DynamicPanelGroupBean {
    private HtmlPanelGroup panelGroup;

    public void refreshPanelGroup() {
        FacesContext context = FacesContext.getCurrentInstance();
        panelGroup = (HtmlPanelGroup) context.getApplication().createComponent(
                HtmlPanelGroup.COMPONENT_TYPE);
        HtmlEditor editor = (HtmlEditor) context.getApplication()
                .createComponent(HtmlEditor.COMPONENT_TYPE);
        panelGroup.getChildren().add(editor);
    }

    public void setPanelGroup(HtmlPanelGroup panelGroup) {
        this.panelGroup = panelGroup;
    }

    public HtmlPanelGroup getPanelGroup() {
        return panelGroup;
    }
}

You can try to wrap the panelGroup in an outputPanel like :

<a4j:outputPanel id="panelGroup">

    <h:panelGroup binding="#{dynamicPanelGroupBean.panelGroup}"/>

</a4j:outputPanel>

Not sure it will change anything but I don't know if the panelGroup is correctly initialize the first time since its a null value in your bean.

Hi Paul,

the a4j:outputPanel did not change anything, but initializing the dynamic panel group in the constructor and a4j:support ajaxSingle="true" ... helped.

Thanks for the hint.
