Passing action in <rich:modalPanel> - jsf

Question

There is some way to pass action in <rich:modalPanel>. I want to write simple popup with "Yes" and "No" button, and I want to reuse this popup in different pages, that's why I need that different action was invoked when "Yes" button pressed. There is a way to pass some value in <rich:modalPanel> with <a4j:actionparam>:
<a4j:commandButton value="See details…" id="det"
reRender="popup_dataIdField, …">
<rich:componentControl for="popup"
operation="show" event="onclick" />
<a4j:actionparam name="message" assignTo="#{popupBean.message}"
value="#{myBean.message}" />
</a4j:commandButton>
But is some way to pass action ?

Answer 1

As you're using Facelets then look at Rick Hightower's article and the section "Passing Actions". It's the same basic method to what you've used, but also passing in the method on the bean.
Eg:
<ui:include src="./WEB-INF/popup/popup.xhtml">
<ui:param name="yesAction" value="save"/>
<ui:param name="cancelAction" value="cancel"/>
<ui:param name="backingBean" value="#{thisPageBean}"/>
</ui:include>
And then in the popup:
<a4j:commandButton id="yesButton" value="#{msgs.yesButton}"
action="#{backingBean[yesAction]}"/>
Note that you use the #.

I find the answer by myself :). Maybe it will be helpful for somebody.
I've done this using Facelets. When I'm include popup to my page I pass parametr to it:
<ui:include src="./WEB-INF/popup/popup.xhtml">
<ui:param name="yesAction" value="${thisPageBean}" />
</ui:include>
Where thisPageBean - is bean from what popup invoked.
Then in my popup I wrote:
<a4j:commandButton id="yesButton" value="#{msgs.yesButton}"
action="#{yesAction.someAtion}"
</a4j:commandButton>
And with this I invoke thisPageBean.someAtion. All magic is ${thisPageBean}, it's is necessary to us $ but no #.

Yes I dont see any problems with doing this. You can use my code if you want:
<rich:modalPanel id="popup" width="261" height="386" autosized="true"left="180" top="200" keepVisualState="true">
<h:panelGrid id="panelGrid">
<h:outputText value="#{PopupBean.output}" id="popupMessage"/>
<a4j:commandLink action="#">
<h:outputText value="Close" />
<rich:componentControl for="popup" operation="hide" event="onclick"/>
</a4j:commandLink>
</h:panelGrid>
</rich:modalPanel>
<h:panelGrid columns="2">
<a4j:commandLink action="#" reRender="panelGrid">
<h:outputText value="Yes" />
<rich:componentControl for="popup" operation="show" event="onclick"/>
<a4j:actionparam name="message" assignTo="#{PopupBean.output}" value="#{TestBean.input1}"/>
</a4j:commandLink>
<a4j:commandLink action="#" reRender="panelGrid">
<h:outputText value="No" />
<rich:componentControl for="popup" operation="show" event="onclick"/>
<a4j:actionparam name="message2" assignTo="#{PopupBean.output}" value="#{TestBean.input2}"/>
</a4j:commandLink>
</h:panelGrid>
Basicly the output in the modal panel will contain the values in the TestBean
Edit (the misunderstanding):
I believe you will have to define your modal panel like this:
<rich:modalPanel id="popup" width="261" height="386" autosized="true"left="180" top="200" keepVisualState="true"
binding="#{PopupBean.popupPanel}">
</rich:modalPanel>
And in your managed bean you will have to addChildren to your modal panel dynamically with java like this:
public String action_PoppingThePanel() {
HtmlCommandButton button = new HtmlCommandButton();
button.setValue("Yes");
String action = "#{TestBean.action_yes}";
MethodExpression methodExpression =
FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
createMethodExpression(FacesContext.getCurrentInstance().getELContext(), action, null,
new Class<?>[0]);
button.setActionExpression(methodExpression);
getPopupPanel().getChildren().add(button);
button = new HtmlCommandButton();
button.setValue("No");
String action = "#{TestBean.action_no}";
methodExpression =
FacesContext.getCurrentInstance().getApplication().getExpressionFactory().
createMethodExpression(FacesContext.getCurrentInstance().getELContext(), action, null,
new Class<?>[0]);
button.setActionExpression(methodExpression);
getPopupPanel().getChildren().add(button);
getPopupPanel().setRendered(true);
getPopupPanel().setShowWhenRendered(true);
return null;
}
