Building Contextual Events with multiple parameters

Question

I am working in JDeveloper 11.1.1.4 and trying to build a contextual event, but ran into a issue that I find unclear. When building the Subscribers on my page definition, in the Property Inspector, how do I define multiple parameters in the customPayLoad element? In all the examples I've found, they reference putting ${payLoad} as the value and they only show one parameter. I need each value to be unique for each parameter. How do I accomplish this?

Answer 1

for this you can use attributes
say suppose if you are using table then you can pass values from producer like
            Map attributes = table.getAttributes();
            attributes.put("param1", param1);
            attributes.put("param2", param2);
            attributes.put("param3", param3);
            attributes.put("param4", param4);and consume it like
    public void handleBusinessChkListEvent(Object payload) {
        SelectionEvent selectionEvent = (SelectionEvent)payload;
        UIComponent component = (UIComponent)selectionEvent.getSource();
        String param1=
            (String)component.getAttributes().get("param1");
        String param2= (String)component.getAttributes().get("param2");
        Boolean param3=
            (Boolean)component.getAttributes().get("param3");
        String param4=
            (String)component.getAttributes().get("param4");
}
