You define the member method "getMyToolId" in your Mixin. This method is
also defined in "qx.ui.core.Widget". The include mechanism allows you
only to add functionality to a given class not to redefine/overwrite
methods. If you need to overwrite this specific method use
"qx.Class.patch" instead.
Do you have FireBug running? FireBug told me nicely what the error was.
Spitting out this exception message:
"[Exception... "'Error: Overwriting member "getMyToolId" of Class
"qx.ui.core.Widget" is not allowed!' when calling method:
[nsIDOMEventListener::handleEvent]" nsresult: "0x8057001c
(NS_ERROR_XPC_JS_THREW_JS_OBJECT)" location: "<unknown>" data: no]"
cheers,
Alex
