svn commit: r561035 - in /lenya/trunk/src/modules: editors/resources/javascript/disablebackspace.js fckeditor/usecases/fckeditor.jx

Author: rfrovarp
Date: Mon Jul 30 09:42:23 2007
New Revision: 561035

URL: http://svn.apache.org/viewvc?view=rev&rev=561035
Log:
New disable backspace code that registers itself merely by being loaded. Change FCK usecase to try to register itself as an event to onload. This would allow for multiple onload's to happen if necessary in the future.
