When using single line mode with StringParameter, you type and when enter is pressed, a change event is sent to flash app. When using multiline, a change event is sent everytime you type any character.
You can test this with rss.swf. Enter mulitline mode for RSS URL. Just type any character and each time the error messages continues to grow for each character you type. Note that the old error messages are not removed either.
In my case I was going to use this so that the VJ could output a text string to the flash app. These strings are appended to a scrolling list of strings. Each time the VJ types any character in multiline mode that new string is sent and this of course is not what you want.
Suggest having some kind of update button rather than depending on the change of text. As it stands, this is worthless to me and I assume to others as well.
