Why wont the softkeyboard show here?
===

I'm in a `DialogFragment` in the `onCreateDialog` I'm using the `InputMethodManager` to show the keyboard when the dialog opens. But, its not working for some reason. Anyone know why?

    		@Override
		public Dialog onCreateDialog(Bundle savedInstanceState) {
			AlertDialog.Builder b = new Builder(getActivity());
			
			b.setMessage("Enter a 5 digit zipcode");
			final EditText et = new EditText(getActivity());
			et.setInputType(InputType.TYPE_CLASS_NUMBER);
			et.requestFocus();
			et.setHint("Zipcode");
			InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(INPUT_METHOD_SERVICE);
			imm.showSoftInput(et, InputMethodManager.SHOW_FORCED);
			b.setView(et);			
			return b.create();
		}
