When adding an <eventChannel type="KEYACTION" key="(ENTER)"> to any component it is not recognized in Mozilla browsers.
The reason is, that the JavaScript function eventChannelKey() in ug2tLibMozilla.js handling that pressed key is asking for the event.charCode instead for the event.keyCode.
Only in the keyCode is sent the key code 13 for the ENTER key - exactly the same as in IE.
In ug2tLibIE.js the code is correctly checking for the keyCode (and not the charCode), so my patch is to do it exactly the same in the Mozilla version of that JS function:
In release 1.8.1 change line no. 751 of ug2tLibMozilla.js from
if (event.charCode==13)
to
if (event.keyCode==13)
and the ENTER key works for key event channels also in Mozilla based browsers.
