Strange Android Back nav behavior

Please, provide the details below:

Did you verify this is a real problem by searching [Stack Overflow]

Yes

Tell us about the problem

Video: https://www.screencast.com/t/1hXgziXKy2oo

So you can see when I navigate back I am clicking around on the items in the Listview (and the events do trigger actually), but no navigation is at all possible. Clicking the back button multiple times though seems to like send me BACK to the “Next” page, like it’s freaking out or something.

Also of note if I use the app and navigate DEEPER (it’s almost like a wizard, like 10 steps deep) the back and forward always works fine, it’s just the one particular simple view that causes the problem… almost like it only happens with 1 item in the navstack.

I even tried doing something like

if(page.isBackNavigation()){
 //frame module code to send them back to home with cleared history
}

…but nothing happens, like I said, all nav functionality freezes ONLY ON BACK

Which platform(s) does your issue occur on?

Okay yeah firebase isn’t needed,

1. Set the loading page in app.ts to “./views/home”
2. Open views\add\step-rotation and set the onNavigatingTo code to

exports.onNavigatingTo = function (args) {
    (<any>global).startTime = new Date();

    indicator = new LoadingIndicator();
    indicator.hide();

    newObservation = new NewObservation();
    page = args.object;

    model = {
        data: new ObservableArray()
    };
    utils.consoleLog("onNavigatingTo");

    model.data.length = 0;
    /*
    Data.GetRotations().then((result) => {
        
    });*/

    var result = [{ "Id": 1, "Name": "Anesthesiology", "Rotation": { "Id": 6, "Name": "Anesthesiology" } }, { "Id": 6, "Name": "Emergency Medicine", "Rotation": { "Id": 19, "Name": "Emergency Medicine" } }, { "Id": 7, "Name": "Family Medicine", "Rotation": { "Id": 22, "Name": "Family Medicine" } }, { "Id": 9, "Name": "Internal Medicine", "Rotation": { "Id": 15, "Name": "Internal Medicine" } }, { "Id": 10, "Name": "Obstetrics and Gynecology", "Rotation": { "Id": 46, "Name": "Obstetrics & Gynecology" } }, { "Id": 11, "Name": "Orthopedic Surgery", "Rotation": { "Id": 47, "Name": "Orthopedic Surgery" } }, { "Id": 12, "Name": "Pediatrics", "Rotation": { "Id": 54, "Name": "Pediatrics" } }, { "Id": 13, "Name": "Psychiatry", "Rotation": { "Id": 26, "Name": "General Psychiatry" } }, { "Id": 8, "Name": "Selectives", "Rotation": { "Id": 60, "Name": "Selective" } }, { "Id": 14, "Name": "Surgery", "Rotation": { "Id": 27, "Name": "General Surgery" } }];
    for (var i = 0; i < result.length; i++) {
        model.data.push(result[i]);
    }

    page.bindingContext = model;

    utils.consoleLog("Stack length: " + frameModule.stack().length);
    utils.consoleLog("Navigation Context: " + JSON.stringify(page.navigationContext));
}

1. In step2-observation just change the onNavigatingTo to this

exports.onNavigatingTo = function(args) {
    page = args.object;
    indicator = new LoadingIndicator();
    indicator.show();
    newObservation = page.navigationContext;

    model = {
        ClerkshipName: newObservation.ClerkshipName,
        data: new ObservableArray()
    };
/*
    Data.GetTypes(newObservation.ClerkshipId).then((result) => {
        for(var i=0;i<result.length;i++){
            model.data.push(result[i]);
        }
        indicator.hide();
    });
*/
    indicator.hide();    
    page.bindingContext = model;
}

WOnt be any callbacks and it replicates

Here we go, sorry about the “size” I left in the platforms so everything would be exactly the same

cd apps cd macdot

the app.ts needs to start on this item moduleName: utils.isLoggedIn() ? “./views/home” : “./views/login/login”

Login needs to be [e-mail] passpasstest123
