display a confirmation popup on button click based on condition

I have a p:commandButton on click of which I need to add a few values to a list. In my managed bean, I'm validating the value that has to be added, and if it validates to false, I have to display a confirmation popup. This is my code - 

<p:commandButton id="add" value="Add" type="submit"                                      action="#{bean.doAdd}" ajax="false"
update=":List"/>

And in the bean, on click of the "Add" button,

public String doAdd() throws Exception {
        if(response != null) {
            if(keyList.contains(response))  {
                if(!responseList.contains(response)) {
                    responseList.add(response);
                } 
            } else {
               //Have to display confirmation popup.
            }
            response = "";
        }

        return response;
    }

I'm using jsf 2.0 and primefaces 3.0. Can someone please tell me how to display the popup from the bean?

You can use RequestContext to run js code inside your managed bean

Make sure its an ajax call - got no ajax="false"

like this

RequestContext context = RequestContext.getCurrentInstance();  
context.execute("YourDialogwidgetVar.show()");

I assume you got some dialog defined...

<p:confirmDialog id="confirmDialog" message="Hello"  
                header="Header" widgetVar="YourDialogwidgetVar">  
</p:confirmDialog>

This code may helpfull to you.

private boolean valid = true; 

public void doAdd() {
    valid = false;
}


<p:dialog id="basicDialog" header="Basic Dialog" visible="#{!testBean.valid}">
    <h:outputText value="Message!" />
</p:dialog>

<h:commandButton id="modalDialogButton" value="Modal" action="#{testBean.doAdd}"/>
