You can call another dialog (lets suppose its widgetVar="anotherDialog") from your managed bean like this:

    public void supprimerPerso() {
    if (condition) {
        RequestContext requestContext = RequestContext.getCurrentInstance();

Note: 1. If you do not pass any parameters to the above method, remember to add braces to method call : actionListener="#{PersonnelMB.supprimerPerso () }". Braces are omitted when parameters are passed. 2. Enable selection and use the selected record for deletion. This makes it easier.

Check showcase for showing listbox in "anotherDialog". Something like this:

<p:dialog header="Selected User for Deletion" widgetVar="anotherDialog" modal="true" showEffect="fade"  resizable="false">
    <p:panelGrid columns="2" id="display" columnClasses="label,output">
        <h:outputText value="Employee ID:" />
        <h:outputText value="#{PersonnelMB.selectedUser.id}" />

        <h:outputText value="Employee Name:" />
        <h:outputText value="#{PersonnelMB.selectedUser.nom}" />
