Oracle Application Express 4.2.2 is now released and available for download. If you wish to download the full release of Oracle Application Express 4.2.2, you can get it from the Downloads page on OTN. If you have Application Express 4.2 or 4.2.1 already installed, then you need to download the APEX 4.2.2 patch set from My Oracle Support. Look up patch number 16277995.
Since APEX 4.0 cascading feature is a part of the standard. Not only a "normal" select list can be cascading but also a shuttle element. In this example I am showing how to filter a shuttle box and move the filtered values to the right side using just one click (change of the first select list).

Also, the number of code lines you need to write is quite moderate. See this example in my demo application:
I always find myself putting an asterisk (if only mentally) next to certain statements. I shall now put all those statements here and link back.

Typically and for good security reasons the password manager from either Firefox or any other browser will not prompt you to save the password for the login screen of the APEX workspace or any of your own APEX applications.
