ExtJS vs. Touch Config System

In this example I will demonstrate the difference between how ExtJS 4 and Sencha Touch 2 config systems treat non-primitives (i.e. arrays or objects). This aspect of the frameworks is very important to distinguish as it will save you from some very painful debugging sessions.

Long story short, Touch will actually clone any objects from the config for every instance of your class, whereas ExtJS will slap them on the prototype (probably not what you want).

Now for a practical example.

Touch 2.2.x is broken in Chrome 29

Chrome 29 came out just two days ago and it appears Sencha Touch 2.2.x projects don't display properly. I'm not sure if it affects mobile Chrome browsers (I assume it would, once they update, but they do lag behind the desktop browser in that department).

A fix posted by Steve Drucker on his blog: http://druckit.wordpress.com/2013/08/22/sencha-touch-2-x-and-google-chrome-29/

Just change the st-box mixin inside of:

/touch2/resources/themes/stylesheets/sencha-touch/base/mixins/_Class.scss

...and recompile the SASS. The new code:

@mixin st-box($important: no) {
    @if $important == important {
        display: flex !important;
        display: -webkit-box !important;
        display: -ms-flexbox !important;
    } @else {
        display: flex;
        display: -webkit-box;
        display: -ms-flexbox;
    }
}
