I have a hidden menu you want to show in a given situation
as follows:

B4X: 
menuActualizacion.VISIBLE = True

B4X: 
Parsing code.                          0.01
Compiling code.                        Error
Error compiling program.
Error description: Unknown member: visible
Occurred on line: 154
menuActualizacion.VISIBLE=True
Word: visible

But it gives me error!

As shown?

You can use the JavaObject to set the visibility of a Menu and it's MenuItems or a single MenuItem

B4X: 
Dim JO As JavaObject = MTest
    JO.RunMethod("setVisible",Array As Object(False))

Small example attached if it helps.

It is starting to feel like a project of any real scope is going to end up with tons of these indirect calls via JavaObjects.

B4J is still young, these things are bound to arise.

Hopefully, with these types of questions and posted solutions, it will make Erel's job easier to see what functions people are using, and use the solutions as a hint as to what needs to be implemented in the base Libraries.

This is correct.

There is also no harm in using JavaObject. Especially for such "simple properties".

You can capture the clik Menu as this has no submenu (MenuIten)

(I think this has to do with this thread.
If not please tell me and put it in a new post)

I have looked at this in the past, although Menu inherits onAction from MenuItem, it appears that the onAction event doesn't fire. There are discussions about it on the internet, with some possible solutions, which I couldn't get to work elegantly. So I just used a sub menu.

That's a more than fair response.

I keep forgetting that B4J: (1.) is still very new, (2.) not backed by a cash- and manpower-rich giant company, (3.) works pretty well even in its current state, (4.) one of few alternatives for writing JVM code in Basic, and of course (5.) free.
