I use Richfaces 3.3.3 GA at my Java Web-Application.
My Users use these Web-Application with Mozilla-Firefox, Safira, IE7, IE8, IE9, ... . . The Web-Application have a Login-Mask: a User log in with user name and password.
I have deactivate "Strg + C" and "Strg + V" and right mouse clicks - but at Mozilla-Firefox a user can copy and insert a password (for example from a text file) with "Strg + mouse clicks".
How can I deactivate "Strg + mouse clicks" at the Logon-Mask with Richfaces?
I don't know how to avoid exactly this combination but you can try a solution from this topic:
There is a js function which defines onpaste event and you can use this event to avoid pasting.
But I'm not sure if it can be used in your case.
