Override show method from a Primefaces context menu

Question

Following the example here I have tried to override the show() mehtod of a Primefaces context menu.

Here my code:

       <p:tree value="#{myTreeBean.mainTreeRoot}" id="myTree>
                       <p:ajax event="contextMenu" listener="#{myTreeBean.onRightClickSelectListener}" oncomplete="PF('serverTreeMenuVar').show()"/>
[...]
        </p:tree>

    <p:contextMenu widgetVar="myTreeMenuVar" for="myTree" id="myTreeMenu" model="#{myBean.contextMenuModel}"></p:contextMenu>

     <script>

                    $( function() {
                        PF('myTreeMenuVar').show = function(e) {
                    console.log('my function');
                    // call the generic implementation:
                    PrimeFaces.widget.ContextMenu.prototype.show.call(this,e);
                }
                    });


    </script>

Unfortunately I get the error:

Uncaught TypeError: Cannot read property 'pageX' of undefined

I'm using PF 7.0

If you used `onclick="PF('myTreeMenuVar').show()"` not work? — vincenzopalazzo, Aug 09 '19 at 08:56
For me it simply works his way. When rightclicking my component the menu occurs and it prints 'my function' to the console. Do you have any other component frame works, JQuery etc. in your project? — Selaron, Aug 09 '19 at 09:18
Argh. Sorry, I had this line in code that was causing the error: Thx for the help — Neo, Aug 09 '19 at 09:39
Great you found the 'error', but then either add the original piece of code into the question in [mcve] flavour and create an answer why it failed or remove the question... — Kukeltje, Aug 09 '19 at 09:43

Override was ok, the problem was caused by the following line:

  <p:ajax event="contextMenu" listener="#{myTreeBean.onRightClickSelectListener}" oncomplete="PF('serverTreeMenuVar').show()"/>

in particular from

oncomplete="PF('serverTreeMenuVar').show()"

So if you'd have started creating a [mcve] by removing a lot from your code including this line, you'd have immediately seen that it was not related to the overriding... That is what [mcve]'s are for... Narrow things down, rooot cause analysis – Kukeltje Aug 09 '19 at 11:14
