You are right man but I had a filling that I didn't initialize variables in a right way.However that wasn't the problem.The problem was that I had trying to get Boundaries Object for new line position of the cursor and that was a cause of the error. I have fix that but now I'm facing with another problem and here is my question:
How can I get the current position(in pixels) of the blinking cursor in a text area and is there a way to set this position programmatically? --- In flexcoders@yahoogroups.com, "Gordon Smith" <[EMAIL PROTECTED]> wrote: > > > I'm getting error cause Boundaries in this case is Null object > > > > Sorry, Branko, but a little code snippet like this isn't enough to > diagnose the problem.
