rerender part of rich:popupPanel

StackOverflow https://stackoverflow.com/questions/13618500

Question

I'm working with:

- RichFaces 4.2.2
- Mojarra 2.1.14

Lets look at simple code below:

<h:form>
    <h:selectOneRadio value="#{testBean.option}" >
        <f:selectItem itemValue="0" itemLabel="Option 0"/>
        <f:selectItem itemValue="1" itemLabel="Option 1"/>
        <f:ajax execute="@this" render="infoPanelId"/>
    </h:selectOneRadio>
    <a4j:outputPanel id="infoPanelId">
        <h:outputText value="Option 0 selected" rendered="#{testBean.option == '0'}"/>
        <h:outputText value="Option 1 selected" rendered="#{testBean.option == '1'}"/>
    </a4j:outputPanel>
</h:form>

and the bean code:

@ManagedBean(name="testBean")
@ViewScoped
public class TestBean implements Serializable{

    private String option;

    public String getOption() {
        return option;
    }

    public void setOption(String option) {
        this.option = option;
    }
}

It works fine, and it is simple. Rerendering works as expected. But if we place this simple code inside rich:popupPanel tag, that code will not work. This is the code snippet:

<h:form>
    <a4j:commandButton 
        value="show popup" 
        oncomplete="#{rich:component('testPopup')}.show()"
        render="testPopup"
    />

    <rich:popupPanel id="testPopup" modal="false" autosized="true" resizable="false">
        <f:facet name="header">
            <h:outputText value="popup"/>
        </f:facet>
        <h:panelGrid columns="1">
            <h:selectOneRadio value="#{testBean.option}" >
                <f:selectItem itemValue="0" itemLabel="Option 0"/>
                <f:selectItem itemValue="1" itemLabel="Option 1"/>
                <f:ajax execute="@this" render="infoPanelId"/>
            </h:selectOneRadio>
        <a4j:outputPanel id="infoPanelId">
                <h:outputText value="Option 0 selected" rendered="#{testBean.option == '0'}"/>
                <h:outputText value="Option 1 selected" rendered="#{testBean.option == '1'}"/>
            </a4j:outputPanel>
        </h:panelGrid>
    </rich:popupPanel>
</h:form>

So the code inside popupPanel does not work. I cannot rerender part of popupPanel. So I have two questions:

  1. why?
  2. How can I make it work?
Was it helpful?

Solution

1) Because by default popupPanel is shown inside the <body> element

2) Adding domElementAttachment="form" to the rich:popupPanel should help
