    Default Broken production build

    hi everyone,
    I am trying to make my first sencha app running and I am facing a lot of issues.
    • My first issue is with microloader, is this a proper index.html file?
    HTML Code:
    <html manifest="" lang="en-US">
        <meta charset="UTF-8">
        <script id="microloader" type="text/javascript" src="js/sencha-sdk/microloader/development.js"></script>
    <div id="appLoadingIndicator"><div></div><div></div><div></div></div>
    As all my .js dependencies are listed in proper order in app.json, I am able to compile my app using sencha app build testing and I can view my app nicely, everything is working as expected.
    • Now I wanted to create release build so I tried sencha app build production and suddenly started seeing
    Error evaluating <a href="http://localhost/.../SomeJS.js" target="_blank" rel="nofollow">http://localhost/.../SomeJS.js</a> with message: ReferenceError: SomeJs is not defined chrome console at runtime
    • I tought maybe chaning microloader/development.js to microloader/production.js would help, but with production.js I am not even able to run production build, I receive:
    [ERROR] TypeError: 'undefined' is not a function

    This issue seems to be frequent all over the web but I was not able to find working solution. My code is compiled fine for testing and throws issues at production? Why is that?
    • Is it necessary to replace microloader for production.js in production build, or build process is smart enough to do this itself?

    Sencha Command will create the index.html for you and when you do a build it will use the appropriate microloader. When I see the undefined is not a function, that usually means you didn't require a class properly.
