Echo Web Framework

Hello,
I/m using te echo3 server side.
I'm using the ActionEvent (which fires when the Enter key is pressed) to store the contained text into a database.

Unfortunately if I want to create a multine comment inside the TextArea, the event is fired also if when I press enter I press simultaneously Shif (to return at new line).

I think this is an unwanted behaviour.

Any idea how to filter out when Shift is Pressed ?

Thank you,
Boris
