Adobe Flex Builder was one of tools, that I wanted to run native after my switch to Ubuntu desktop. Adobe released alfa version of  Flex builder build on top of Eclipse IDE.  Because my workstation is amd64, it is not so easy to install as on x86 architecture.

While I was working on Flex application that was integrated as desktop application using Adobe AIR, I face this very strange issue. While I was entering text into TextField, all previously entered text disappears after pressing Shift+4/č! It was really frustrating bug not only from user experience point of view . So how to fix it if it is out of your control? Simplest way is to wait for a fix from Adobe, but I was not my case.  I wrote a small workaround. It is not ideal, because all these workarounds are for certain cost.  I created a small method for filtering wrong inputs and correct them. Yes, it is not so nice, but it saved my project timeline .

public static function fixTextInput(event:KeyboardEvent) : void {
  if ((event.charCode == 13) && (event.keyCode == 52)) {
    event.preventDefault();
    var control:TextInput = TextInput(event.currentTarget);
    if (event.shiftKey) {
      control.text = control.text.substring(0,control.selectionBeginIndex) + "4" + control.text.substring(control.selectionBeginIndex,control.text.length);
    } else {
      control.text = control.text.substring(0,control.selectionBeginIndex) + "č" + control.text.substring(control.selectionBeginIndex,control.text.length);
    }
    control.setSelection(control.selectionBeginIndex + 1, control.selectionBeginIndex + 1);
  }
}
