   I'm experiencing this issue too, and I can't find a workaround. I'm seeing it with both 1.5.1 and 1.4.2 SDKs. Since it seems to only be an issue when compiling for a device, and I'm only seeing this issue for tab groups (a straightforward app.js that loads a single window works, while the same code but with a tab group doesn't) I found all files within the build directory that seem to reference a tab group. There are differences between a simulator build and a device build, but I'll leave it to you to decide if that's unnatural. Just thought this might be useful!

   I'd really appreciate a fix or a workaround for this, since it's pretty much a showstopper for us.

   Cheers,

   I've found the issue, but not the cause. The defines.h file is missing includes for all the titanium UI components I'm using in the application. When running the code in the simulator all components are included by default, whereas when building for a device the includes are done dynamically. What's probably happening is Titanium isn't picking up on the use of the modules in the code, and not including them in the file.

   Are you using the helium library by any chance? I'm wondering if that, or its advocated practice of loading components in a separate scope, is contributing to this issue.

   When we debugged this issue and messed around for ages with it, we found it was because we didn't have a tab in place, our app wasn't using tabs to begin with and this seemed to cause issues, we put some tabs in and everything went back to normal...

4. Craig Marvelley 2011-04-15

   Yeah, I think I've the same problem but with a different cause - I'm adding tabs to the group but not in the global scope, and it doesn't look like they're being picked up.

   This is a limitation of the compiler when you don't explicitly use createTab in your code, but can be worked around.

   The bundler tries to only include modules that it needs to in order to keep the footprint of your app relatively small (in file-size). In order to do this, the compiler tries to determine what modules you are using in your project and only includes those in the final .app package. It looks for Titanium 'create' functions (such as createButton, createLabel, createTabGroup, createTableView, etc.).

   In a normal project where you do something along the lines:

      Ti.UI.createTableView(...);
      Ti.UI.createTabGroup();
      Ti.UI.createTab({...});
      Ti.UI.createTab({...});
      Ti.UI.createTab({...});
      

   Based on the parsing mechanism that it uses, the compiler comes away with the following unique modules:

   • TABLEVIEW
   • TABGROUP
   • TAB

   However, the class files for all the tab class files checks for just TAB (not TABGROUP)... as seen here from TiUITabGroupProxy.h:

      #ifdef USE_TI_UITAB
      #endif
      

   ...so unless you explicitly call TI.UI.createTab(...) in your code somewhere, you will run into this issue.

   An easy solution would be to put:

      Ti.UI.createTabGroup;
      

   Somewhere in your app.js file.

   The permanent fix would be to change the compiler to merge TAB and TABGROUP into one, or change the header files to respect either constant (USE_TI_UITAB || USE_TI_UITABGROUP).

   I have the same problem. After building a hw build my defines.h becomes like this:

   // Warning: this is generated file. Do not modify!

   define TI_VERSION 1.6.1

   define USE_TI_ANALYTICS 1

   define USE_TI_NETWORK 1

   define USE_TI_PLATFORM 1

   define USE_TI_UI 1

   define USE_TI_INCLUDE 1

   define USE_TI_UIALERTDIALOG 1

   define USE_TI_API 1

   define USE_TI_APIINFO 1

   define USE_TI_PLATFORMID 1

   define USE_TI_NETWORKHTTPCLIENT 1

   I'm using Titanium 1.6.1, XCode 4 for the iPhone

7. Daniel Arroyo 2011-04-15

   even more info:

   It seems that I was able to fix this by taking my code out of the /Resources/iphone directory into the /Resources directory.

   I'm guessing this is regression for 1.6.1 ?

10. Junaid Younus 2012-08-23 Tested Dustin's code on the iOS simulator using TiSDK 2.2.0v20120821095711, I get the following console output:
