Jason,
Thanks for this. As you say, if I continue using the .text
attribute it will still work but
will remove the html formatting which isn't what I want.
I tried using your routine which removes the last character or tag
from a html text and it
doesn't quite do what I need. The main problem is that the
"maxscroll" property for htmlText seems
to behave in a different way to normal text and almost always seems
to be greater than 1 regardless of
how many times you call getTextMinusOneCharacter - this results in
the input field removing text which should
be kept.
Anymore thoughts on this would be welcome.

Try using your original handler function even though the text field is
now HTML-enabled, because removing the last 'htmlText' character simply
pops off a (non-visible) closing tag's (likely </textformat>) final
angle bracket.
If this method destroys HTML formatting on your text, you can always use
the following code.
function getTextMinusOneCharacter(targetText:String,
presumeHTML:Boolean):String
{
var lastBracketIndex:Number = targetText.lastIndexOf('<');
while (lastBracketIndex > 0 && targetText.charAt(lastBracketIndex - 1)
== '>')
{
lastBracketIndex = targetText.lastIndexOf('<', lastBracketIndex -
1);
}
lastBracketIndex--;
if (lastBracketIndex > 0 && presumeHTML !== false)
{
targetText = targetText.slice(0, lastBracketIndex) +
targetText.slice(lastBracketIndex + 1);
}
else
{
targetText = targetText.slice(0, targetText.length - 1);
}
return targetText;
}
this.textBox.onChanged = function():Void
{
if (this.maxscroll > 1)
{
this.htmlText =
this._parent.getTextMinusOneCharacter(this.htmlText);
}
};

I'm trying to restrict text input into a field so that you can only
enter as much as will fit into the field and the rest gets cut off.
I was using code like
textBox.onChanged = function() {
while (this.maxscroll>1) {
this.text = this.text.substr(0,-1);
}
}
This works fine as long as its just plain text. However I need to use
html text so that the user can apply formatting.
If I try using
textBox.onChanged = function() {
while (this.maxscroll>1) {
this.htmlText = this.htmlText.substr(0,-1);
}
}
then Flash goes into an infinite loop. I did some debugging and it
looks like the value of maxscroll isn't the same for htmlText and so
removing the last character doesn't reduce maxscroll in the same way,
