RE: [flexcoders] getParagraphLength method error!!!!

Here is a simple application incorporating your code snippet. As I click in the TextArea, I don't get any errors. So you'll need to post your exact code and the exact sequence of user interactions that lead to your problem. What is the value of caretIndex when you get the error?

Subject: [flexcoders] getParagraphLength method error!!!!

var caretIndex:int = textArea.getTextField().caretIndex;
var beginIndex:int =
textArea.getTextField().getFirstCharInParagraph(caretIndex);
var endIndex:int = textArea.getTextField().getParagraphLength(caretIndex);

and I'm getting error like "The supplied index is out of bounds."

And here is the deffinitoin of getParagraphLength property:

getParagraphLength () method

public function getParagraphLength(charIndex:int):int

Parameters charIndex:int — The zero-based index value of the
character (for example, the first character is 0, the second character
is 1, and so on).

Returns int — Returns the number of characters in the paragraph.

Please tell me what is wrong with my code?
