B4J Question Weird Menu JSON Error.

[LWGShane]

I'm re-doing the menu for my app and am receiving a "Value at 2 is null" error.

The Menu Code:

[
    {Text: "File", Children:
    [
        {Text: "Open Image", Tag: "Open"},
        {Text: "Exit", Tag: "Exit"},
    ]},
    {Text: "Generate", Tag: "Generate", Children:
    [
        {Text: "All"},
        {Text: "Development Platforms"},
        {Text: "Social Platforms"},
        {Text: "-"},
        {Text: "Android"},
        {Text: "iOS"},
        {Text: "Windows", Children:
        [
            {Text: "Phone 8.0"},
            {Text: "Windows 10 Universal"},
        ]},
    ]},
    {Text: "Write", Tag: "Write"},
    {Text: "Help", Children:
    [
        {Text: "About"},
        {Text: "BitBucket Repository"},
    ]},
]

The Error Code:

Any ideas?

Your JSON is invalid according to the site I use; https://jsonformatter.curiousconcept.com/

I'm using the JSON format provided by Erel from this thread. It should work, yet it doesn't.

I got your menu working but can't post it as it goes screwy in the forum here's the zip

 

[Daestrum]

I think the main problem was the 'Write' top menu with no children, as that would have been item 2.

That's correct. Top menu items must have a children element.

@Daestrum Thanks for the help!

@Erel - First time designing a menu by hand, so I wasn't used to all of the quirks of the menu JSON.
