My Edit boxes don't work anymore

Its probably something stupid, but I have noticed that my Edit boxes don't work. They used to, ages ago when I last tested them. It could possibly be since I updated to MyGUI3.0.1.
I get focus, I can click in them and even select and delete text. But if I type letters nothing comes out.
I'm definitely injecting key presses:
virtual bool keyPressed( const OIS::KeyEvent& vEvent ) {
gui.getGuiManager()->injectKeyPress(MyGUI::KeyCode::Enum(vEvent.key));


Did any change happen in the v3 update perhaps that might affect edit widgets? Any ideas what my problem points to?

Now you also need to give character code to MyGUI, here's code used in demos:
MyGUI::Char translateWin32Text(MyGUI::KeyCode kc)
{
static WCHAR deadKey = 0;

BYTE keyState[256];
HKL layout = GetKeyboardLayout(0);
if ( GetKeyboardState(keyState) == 0 )
return 0;

int code = *((int*)&kc);
unsigned int vk = MapVirtualKeyEx((UINT)code, 3, layout);
if ( vk == 0 )
return 0;

WCHAR buff[3] = { 0, 0, 0 };
int ascii = ToUnicodeEx(vk, (UINT)code, keyState, buff, 3, 0, layout);
if (ascii == 1 && deadKey != '\0' )
{
// A dead key is stored and we have just converted a character key
// Combine the two into a single character
WCHAR wcBuff[3] = { buff[0], deadKey, '\0' };
WCHAR out[3];

deadKey = '\0';
if(FoldStringW(MAP_PRECOMPOSED, (LPWSTR)wcBuff, 3, (LPWSTR)out, 3))
return out[0];
}
else if (ascii == 1)
{
// We have a single character
deadKey = '\0';
return buff[0];
}
else if(ascii == 2)
{
// Convert a non-combining diacritical mark into a combining diacritical mark
// Combining versions range from 0x300 to 0x36F; only 5 (for French) have been mapped below
// http://www.fileformat.info/info/unicode/block/combining_diacritical_marks/images.htm
switch(buff[0]) {
case 0x5E: // Circumflex accent: в
deadKey = 0x302; break;
case 0x60: // Grave accent: а
deadKey = 0x300; break;
case 0xA8: // Diaeresis: ь
deadKey = 0x308; break;
case 0xB4: // Acute accent: й
deadKey = 0x301; break;
case 0xB8: // Cedilla: з
deadKey = 0x327; break;
default:
deadKey = buff[0]; break;
}
}

return 0;
}

bool InputManager::keyPressed(const OIS::KeyEvent& _arg)
{
MyGUI::Char text = (MyGUI::Char)_arg.text;
MyGUI::KeyCode key = MyGUI::KeyCode::Enum(_arg.key);
int scan_code = key.toValue();

if (scan_code > 70 && scan_code < 84)
{
static MyGUI::Char nums[13] = { 55, 56, 57, 45, 52, 53, 54, 43, 49, 50, 51, 48, 46 };
text = nums[scan_code-71];
}
else if (key == MyGUI::KeyCode::Divide)
{
text = '/';
}
else
{
#if MYGUI_PLATFORM == MYGUI_PLATFORM_WIN32
text = translateWin32Text(key);
#endif
}

MyGUI::InputManager::getInstance().injectKeyPress(key, text);
return true;
}

You can use much shorter variant - something like gui.getGuiManager()->injectKeyPress(MyGUI::KeyCode::Enum(vEvent.key), (MyGUI::Char)vEvent.text);but OIS not always gives proper characters.

Thank you very much!
