#8634 closed Bug (fixed)

The editor.execCommand('cut') returns true instead of false, on IE

Whilst trying to make use of the existing 'cut' command, within the clipboard plugin, I encountered a problem where editor.execCommand('cut') was always returning true on IE, even though browser settings prevented automatic execution of cut/copy operations.

Delving a bit deeper, it looks like execIECommand() in the plugins/clipboard/plugin.js returns 0 or 1 which is eventually compared to false (using the !== operator) in core/command.js, line 52. Modifying execIECommand() to set enabled to false or true (instead of 0 or 1) seems to resolve the problem.

REproducible from CKEditor 3.4.2 rev [5949]

Changing false/true

var	enabled = false;
var onExec = function()
	enabled = true;

to 0/1

var	enabled = 0;
var onExec = function()
	enabled = 1;

resulted in constant true being returned when comparing it to:

return ( this, editor, data ) !== false );
