Disabling an entry gives " Cannot read property 'data' of null"

[crystalfp]

I'm using 3.0.0-beta.2 inside Chrome.
To update the enabled/disabled status of an entry of the menu the only solution I have found is to put a

disable: (): boolean => {
	return projectStatus === "ACTIVE";
}

in the entry and then have:

events: {
	show: (): boolean => {
		$.contextMenu("update");
		return true;
}

But when I open the menu the following error appears:

ContextMenuOperations.js:488 Uncaught TypeError: Cannot read property 'data' of null
    at HTMLUListElement.<anonymous> (ContextMenuOperations.js:488)

Is this the correct way or there is another method to be used to enable/disable an entry (and change the name, but this is the next step).
Thanks for looking!

Dirty workaround found.
In node_modules/jquery-contextmenu/dist/jquery.contextMenu.js change line 994 to:

                // e.data.manager.operations.resize(e, $(element), true);
                element.data.manager.operations.resize(e, $(element), true);

Then comment line 1015

                // rootMenuData.manager.operations.resize(e, currentMenuData.$menu);

In my previous entry correct disable: to disabled:
And now, at least for me, it works!
BTW, I'm using beta 3.x
Hope this project revives, It is so useful and I don't have found any alternative so powerful and flexible.
Thanks!
