[Seaside] Getting the selected text in a textArea

[Avi Shefi]

Bernat,
You can either use Javascript to put the selected text into some hidden
element, which on callback will be available as an element value, or you can
use Ajax to send the value back (instead of submitting it using an onClick
event).


Regards,
Avi.
