App crashed when move from a Window to Menu

[johnlamhc]

The app will be crashed while going from a Window to a Menu or return (click the back button) from a Window to a Menu.

[johnlamhc]

Example

Code:

//about window
function aboutWindow() {
  var aboutWindow = new UI.Window({ status: true });

  var bgRect = new UI.Rect({
    position: new Vector2(0, 0),
    size: new Vector2(144, 168),
    backgroundColor: 'white'
  });

  aboutWindow.add(bgRect);

  var logo = new UI.Image({
    position: new Vector2(32, 10),
    size: new Vector2(80, 80),
    image: 'images/Pebble-logo Large.png'
  });

  aboutWindow.add(logo);

  var titleText = new UI.Text({
    position: new Vector2(0, 90),
    size: new Vector2(144, 48),
    text: 'by johnlamhc',
    font: 'gothic-24',
    color: 'black',
    textAlign: 'center'
  });

  aboutWindow.add(titleText);

  aboutWindow.on('click', 'select', function(e) {
    aboutMenu();
  });

  aboutWindow.show();
}
//end of about window

//about menu
function aboutMenu() {
  var aboutMenu = new UI.Menu({
    sections: [{
      title: 'App Info',
      items: [{
        title: 'App Name',
        subtitle: 'Pebble.js',
      }, {
        title: 'Version',
        subtitle: '1.9.9 (2016/05/13)',
      }, {
        title: 'Creator',
        subtitle: 'johnlamhc',
      }, {
        title: 'Copyright',
      }]
    }, {
      title: 'Requirements',
      items: [{
        title: 'JSON (Pebble)',
        subtitle: '1.0.8',
      }]
    }]
  });

  //onSelect
  aboutMenu.on('select', function(e) {
    console.log('About' + [e.itemIndex]);
    if ([e.itemIndex] == 3) {
      copyrightCard();
    }
  });

  aboutMenu.show();
}
//end of about menu

When I am at "aboutWindow" and make a click, where the correct response will be jump to "aboutMenu", but the app crashed and give me the following error message:

ault_handling.c:79: App fault! {084ad721-fd3a-4321-a331-5d576478b861} PC: 0x50169042 LR: 0x805b839

[Meiguro]

Thanks for posting a minimal example!

In your testing, does this issue occur on Aplite and Basalt? It's possible the image is on the larger side, but I will verify on my end.

[johnlamhc]

I have tried and this issue happens on both Aplite and Basalt.

[matopeto]

I have same issue.

Return from card to menu.

All platforms (emulators and watches). Compiled in CloudPebble.

[linuws]

This is not an issue for me any more. After some updates to CloudPebble it just started to work again. I'm using a Pebble Time (compiling for basalt + chalk). I have no idea what fixed the issue tho' - but try to compile one more time and see if works for you as well :)

[matopeto]

Still issue for me. I will try add minimal example that do not work for me.

[matopeto]

This is example that don't work for me (return from card to menu crashes the app)

                }
            ]

[pieteroskam]

I'm also encoutering this problem. matopeto, did you fix it?

[matopeto]

@pieteroskam no I dont fix it, only workaround that works for me was trimming text length on card to cca 100 characters. (I think only windows with more content cause this issue)

[andrei-markeev]

Same stuff happens for me at least on Aplite - but not always, seems to be related to size of the body text or maybe some non-standard symbols in it.

[dnschneid]

Yeah, for my app, it is dependent on the amount of text in the card. 436 characters result in a crash on returning to the menu, but 418 characters are OK. It's the same limit on all three platforms.

[rutgerkra]

Is there any fix for this issue yet? I use a menu window to start a game window and after some interaction within the second window it crashed when called hide() instead of returning to the initial menu window. I think it's a memory issue, since it only comes up when some threshold is crossed in the second window...

Removed everything from the card. Still problems.
Found that if i removed the banner in the card it did not crash.

[johnlamhc]

@unk1nd Any code same for the "banner" you mentioned? Thanks.

[unk1nd]

resultsMenu.on('select', function(e) {
      // Get server info
      var serverinfo = data.servers[e.itemIndex];
              
      // Assemble body string
      // 
      var content = "\nLast Seen:\n"+ serverinfo.last_update + "\n" +"\nIP: "+ serverinfo.ip + "\nHostname: "+ serverinfo.hostname + "\nAdmin: "+ serverinfo.admin + "\nLoad: "+ serverinfo.load;
      console.log('Showing info about ' + serverinfo.box);
      
      var BoxName = serverinfo.box;
      
      var icon_status = data.servers[e.itemIndex].status;
      var banner = "";
      if(icon_status == "Up"){
          banner = server_icon_up; 
      }
      if(icon_status != "Up"){
          banner = server_icon_down;
      }
      // Create the Card for detailed view
      var detailCard = new UI.Card({
        status: false,
        title: ' ' + BoxName,
        titleColor: '#899986',
        icon: title_icon,
        banner: banner,
        style: 'mono',
        body: content,
        bodyColor: '#ffffff',
        backgroundColor: '#336699',
        scrollable: true,
        action: {
          up: 'images/action_icon_up.png',
          down: 'images/action_icon_down.png',
          backgroundColor: '#e5e845',
        }
      });
      detailCard.show();
  });

This is the card code i use in my pebble.js app.
It parses 3 items in a JSON from my server.
Only one of them fail if i use banner and banner = server_icon_up.
The image is a 4kb png image and from what i can see in the debug logs it is not eating up memory.

Let me know if you need more info. Don't want to share all of the code.

[matopeto]

Upping this bug, still happends with new package system.

Simplest code is:

/**
 * Welcome to Pebble.js!
 *
 * This is where you write your app.
 */

require('pebblejs') ;
var UI = require('pebblejs/ui');

var menu = new UI.Menu({
    sections: [
        {
            items: [
                {
                    title: "item1",
                }
            ]
        }
    ]
});

menu.on('select', function(e) {
    var card = new UI.Card(
        {"title":"Dopravní uzavírky a omezení",
         "body":"ulice Gustava Geipela, mezi křižovatkami ulic Okružní a Hlavní, Aš, okr.

         "scrollable":true,
         "style":"large",
         "status":false
        }
    );
    card.show();
});


menu.show();
