PrimeFaces dynamic cotextmenu and actions

[Gert Jan Kruizinga]

Hi all,


I am working on a application using the context menu in the datatable from PrimeFaces 3.0.M4

If i define the context menu in the xhtml i can use the following:

            <p:contextMenu for="agendaTable">
                <p:menuitem value="Bekijken" />
                <p:menuitem value="Bewerken" action="#{agenda.doEditButton}" />
                <p:menuitem value="Kopiëren" action="#{agenda.doCopyButton}" />
                <p:menuitem value="Verwijderen" action="#{agenda.doDeleteButton}" />
            </p:contextMenu>

But i need to generate the context menu from the backingbean, i use the following:

    public MenuModel getMenuModel() {
        MenuModel menuModel = new DefaultMenuModel();
        MenuItem item = null;
        
        if (bController.isPermitted("Agenda:New:*")) {
            item = new MenuItem();
            item.setId("popup_edit");
            item.setValue("Bewerken");
            item.setDisabled(isNewButtonDisabled());
            item.addActionListener(???);
        }
        menuModel.addMenuItem(item);
        
        return menuModel;
    }

But MenuItem#addActionListener takes a class impementing ActionListener as parameter. How can i assign the dynamically generated menuItem to my simple method #{agenda.doEditButton} like i do from the xhtml?

I don't think a direct linkage is possible there. More likely, you're going to have to build up some EL infrastructure and bind the actions as EL expressions just as you did in the raw XML version of the control definition. A bit ugly, but not an uncommon practice.

Thank you for your answer Tim but i'm not sure that i understand it.

All i want to do is call the public method "doEditButton()" from my bean named "agenda" and you tell me that that is not (easely) possible from a dynamicly generated menu while it is common practice if i do it from xhtml?

I used the #{a.b} format to illustrate that i want to call that function, like i do in xhtml.

item.addActionListener(doEditButton())

does not work.
