How to invoke the softKeyboard for a TLF textfield in AS3?

Question

Hi,
I need to use a TLF textfield in a Flash mobile app.
How to invoke the softKeyboard on mobile devices for such a TLF textfield? I tried it the way below, but it's not showing up:
import flash.ui.Keyboard;
import flash.events.KeyboardEvent;
import flash.events.SoftKeyboardEvent;
chat.needsSoftKeyboard = true
chat.requestSoftKeyboard()
(I can't use a "classic textfield" for a couple of reasons)
Any tips welcome

If you had something like this :
<FORM name="checkform">
<input type="text" name="myText" size="5">
<select size="1" name="select" onChange="check()">
<option value="1">Number1
<option value="2" selected>Number2
</select>
</FORM>Your javascript funtion would look like this :
<script language="JavaScript">
function check() {
     if (this.checkform.select.options[this.checkform.select.selectedIndex].value == "1") {
          this.checkform.myText.size = "20"
     } else {
          this.checkform.myText.size = "5"
</script>Note the names of the form (checkform) and the input field (myText).
