no ones had this problem befor? maybe we should suggest this feature to adobe
With a question like this, the best place to look first is the language reference rather than the forum. Just type flex 3 language reference in google, then select the component you are working with, and it will list all of the properties and methods of the component.
For TextArea, the language reference lists the following properties, which are probably what you are looking for:The zero-based character index value of the first character in the current selection.The zero-based index of the position afterthe last character in the current selection (equivalent to the one-based index of the last character).
ooo i thought those only worked when text was highlighted, kinda makes sense but still i think adobe should implement this feature better.
