[TIMOB-3132] iOS: Platform Specific JS Not Considered in Build Scripts Exclusion Process

Problem

Platform specific JavaScript files are not considered when the build scripts decide what modules to exclude. That means if you only use Ti.UI.createWindow in a platform specific JavaScript file, you will NOT be able to deploy to device. NOTE: This will ONLY show up when you deploy to device! The simulator build scripts don't exclude modules, so this bug will not show up there.

Error

When deploying to device, the following error will pop up:

Application Error
invalid method (createWindow) passed to UIModule at createWindow.js (line 2)

Sample Code

Place the following in your Resources/app.js. Note that you can uncomment the last line to force the build scripts to include Ti.UI.Window.

// include a file that attempts to create a new window
// if this file is in the platform build folder, its content won't be used to decide what modules to include
Ti.include('createWindow.js');

// so if we explicitly specify "we're going to use Ti.UI.Window", this program will work
// but if you comment out the following line, and deploy to device, this app will NOT work
//Ti.UI.createWindow;

Now place the following in Resources/iphone/createWindow.js. Note that if you move it to Resources/createWindow.js (out of the iphone folder), everything will work.

var win = Ti.UI.createWindow({
    backgroundColor: '#0f0'
});
win.open();

If everything works (if the bug is NOT present), you will see a window with a green background.

Tested On

Titanium SDK version: 1.6.0 (02/10/11 14:34 9db0685...) WORKS on iPhone Simulator 4.2 BROKEN on iPod Touch 3rd Generation WORKS on Android Device 2.1 (when placed in Resources/android folder)

Workaround

Either move the code out of the iphone folder, or explicitly force Titanium to include the components that are being excluded by placing the following in your app.js:

Ti.UI.createWindow; // note that we don't actually call this function; just a reference is enough
