Hi mutturaj, Is it possible for you to provide a reproducible test case in the form of an app.js? I also need you to add the Titanium Mobile SDK version you are building against, and the Android OS version. Thanks.

I've set this to resolved so that the issue can now be edited to provide more info. We appreciate your time in helping to improve our platform. Thanks, Daniel

I can confirm this problem. For me it just randomly shows this message when accessing the property, but it not always fails. Lets say 1 in 100 times this error occurs *. Just run this a thousand times to test: alert(Titanium.Platform.displayCaps.platformWidth); It for sure happens in SDK: 3.0.2.GA Maybe it is fixed in the new SDK 3.1.0, It's not easy to test, because in my case there is no noticeable reason.

Hi Michael, I tried this code with 3.1 GA... It never seems to fail for me. Please try with 3.1 GA and let me know how it goes.

var win = Ti.UI.createWindow({
   	backgroundColor : "#FFF"
   });
   win.addEventListener('click', function(e) {
   	alert(Titanium.Platform.displayCaps.platformWidth);
   });
   win.open();

Thanks.

I get this error randomly, but most of the time. function tabWidth() { return Ti.Platform.displayCaps.platformWidth / 2; }

Did you try my test case? Which Ti SDK version?

The error occurs when the application is initialized from a uri with a intent filter, here is the code: https://github.com/appcelerator-titans/App/blob/master/Community/Resources/android/ui/TabStripView.js SDK Version: 3.1.0.GA

   <activities>
     <activity url="app.js">
       <intent-filter>
         <data android:scheme="cascanner"/>
         <action android:name="android.intent.action.MAIN"/>
         <category android:name="android.intent.category.DEFAULT"/>
         <action android:name="android.intent.action.VIEW"/>
         <category android:name="android.intent.category.BROWSABLE"/>
       </intent-filter>
     </activity>
    </activities>

We are also facing the similar issue and it is very random. We have got it once twice till now in 1.5 month. But we are unable to create a reproducible test case for this. But this is existing and extremely rare. Gilberto, Can you please explain as to what did you mean by application initialized URI. Above is the intent filters that we are using for our app. We are testing it with 3.1.0GA
