I am building a very simple app that have 2 tabs. I am mimic the sample provided by ionic web site (tabs). So I have my main index.html, a tabs.html (for the tab navigation footer) and 2 more html files with the content of the tabs (actually just simple text at the moment). When I run my application (http://localhost:8100) the page is correctly forwarded to the default tab address (http://localhost:8100/#/tab/b2bviewer) and the tab footer with tabs icons is displayed. But no content in the page. If I click the second tab (setting) the url change correctly (http://localhost:8100/#/tab/settings) but still blank page. All this without a single error in the browser console.
So my first question is: how can I troubleshoot such situation? Wrong behaviour and nothing in the log. I added a couple of console.log in my .js but I can just see that the js has been executed.
Second question is: what's wrong in my app!? Here some bits and pieced of my code:
index.html
<!DOCTYPE html>
<html ng-app="b2bviewerApp">
<head>
<meta charset="utf-8">
<meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no, width=device-width">

<!-- IF using Sass (run gulp sass first), then uncomment below and remove the CSS includes above
<link href="css/ionic.app.css" rel="stylesheet">

<!-- ionic/angularjs js -->

.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {

})

view: {

// if none of the above states are matched, use this as the fallback
$urlRouterProvider.otherwise('/tab/b2bviewer');
});

Any help is help is much appreciated.

There are a few problems with your code.
When you define a state you specify a view using views instead of view:
.state('tab.b2bviewer', {
url: '/b2bviewer',
cache: false,
views: {
'tab-b2bviewer': {
templateUrl: 'templates/tab-b2bviewer.html',
controller: 'B2bviewerController'
}
}
})
You don't have the template tab-b2bviewer.html (or maybe you haven't included here).
You have misspelled your views's name in the tab:
<!-- b2bviewer Tab -->
<ion-tab title="b2bviewr" icon-off="ion-ios-pulse" icon-on="ion-ios-pulse-strong" href="#/tab/b2bviewer">
<ion-nav-view name="tab-b2bviewr"></ion-nav-view>
</ion-tab>
You've used tab-b2bviewr and it should be tab-b2bviewr.
