Steps to reproduce: 1. Launch attached zip to an iOS Simulator 2. In the app, go to *Users > Login User*. Login using *a/1234* 3. Next, go to Custom Objects > Create Object 4. Specify a class name and property key. Then, press *Add New Property* 5. In the newly created text field, type a word using your keyboard (not soft keyboard) e.g. *green* 6. Wait for the autocapitalization hint to appear (see green.png) 7. Press enter on your keyboard 8. Go to http://cloud.appcelerator.com/38ff33d9-dc4d-4fd3-bd71-c7e84efe216c/objects. Login using *luuwilson+acs@gmail.com/1234*. Make sure development tab is selected. Actual: Capitalized word is appended to existing word. See bug.png Expected: The capitalized word should not be appended to exiting word. Note: * This is not a regression * This bug does not occur on Android devices/emulators or iOS devices * Source code is in Resources/window/customObjects/create.js ** Look at doCreateNewProperty() and submitForm()
