Blank screen occurs with only partial header when using later versions of Ionic


I have been using Ionic for a couple of months now, with IBM Worklight to create an hybrid app. I’ve been using Ionic 1.0.0beta1, and it works and displays all the content fine for me. However, when I upgrade to the later versions of Ionic, I get a blank page on my main page which has an ion-side-menus & ion-side-menu-content tags with only part of the header showing on screen.

Could someone let me know what changed in the recent versions that would causes a blank screen when using ionic tags?(It could be an IBM Worklight issue also) (I would hate to have to stay with version beta1 and miss out on all the other upgrades and fixes.

Note: All my ionic side menus and content tags look fine and display without issue in version ionic 1.0.0beta1.

Can you provide some code, maybe any errors from iOSs remote debugging. Kind of hard to know the issue with out this.

Here’s my code for home page
/****** home.html ******/

<div ng-controller="homeCtrl">
<ion-side-menus >
<ion-header-bar align-title="center" class="bar-positive ">
<button ng-click="toggleLeftSideMenu()" class="button button-icon icon ion-navicon"></button>
<div class="button-bar colorOutlineWhite" style="margin-left:20px;margin-right:20px;">
           <a class="button button-small leftRoundedButton"> Left</a>
           <a class="button button-small rightRoundedButton">Right</a>                             
<button class="button button-icon icon ion-plus-circled"></button>
   <ion-content style="margin-bottom:-35px; margin-top:10% !important;">
       <h3 >Testing</h3>
           <ion-item class="item item-thumbnail-left">

When I use ionic beta v1, I can see the content

When I use the later versions of ionic(here, I’m using IonicBetaV8), I see this

The issue is probably coming from here.

 <script src="angular/angular-route.js"></script>

No need to include this, ionic.bundle comes with ui-router.

And here.

<div ng-view></div>

use <ion-nav-view></ion-nav-view> instead

Plus this…

<body style="display: none;">

I found this discussion and hack for Ionic.bundle


and applied it to the ionic.bundle.js

Still no luck.

However, when I switched back to using ng-route instead of ui-router, I started to see something on screen. I added padding-bottom to ng-view and the header bar started to reveal itself. I added about 1000px(just to see what would happen) of padding-bottom and the view is completely visible.

 <div ng-view class="addpadding"></div>

I wonder if ui-router is having some issue blocking content or worklight could be blocking the content.

By switching back to using ng-route and adding some padding to the ng-view, it seemed to fix my issue.

When I tried the same hack/fix using

ui-router and <ion-nav-view> 

the issue still occurs.

It looks like I may have to use ng-route while using work light and ionic together. Worklight and/or ui-router must be causing a white block to appear over content displayed on screen.

One oohing thing I noticed though. When I added the padding-bottom to the view, it affects the scrolling of lists on screen. Now, I need to figure out how to over come this issue.

I just realized something. I removed the platform hack from my code and kept the padding-bottom to the

and I’m still able to see the view. This leads me to believe something is up with angular and/or ng-view.
