applyLink Not Removing Existing Hyperlinks?

Hi Richard,

Below is my code. I am first building my rich text editor as a component for Flex 3. I've stripped out a lot of the UI and event handlers, and just focused on the two hyperlinking functons; and how some of the TLF essentials have been implemented. It sounded to me from your explanation like you performed one extra step before calling applyLink for removal.

rdermer wrote: I ran a simple test where I created a link and then selected it, set the link to null and called applyLink again.  The formatting dissapeared as expected.

Not sure what this meant, or if I am missing something. Please review and comment; thanks!

Cheers,

Matt
