getting com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.CKEDITOR is undefined error

[Akshay Lokur]

Hello,

I am trying to add CKEditor in my UiBinder based GWT app.

But getting following  exception:

00:00:05.216 [ERROR] Unable to load module entry point class com.lokur.admin.usp.motd.client.MessageOfTheDay (see associated exception for details)

com.google.gwt.user.client.ui.AttachDetachException: One or more exceptions caught, see full set in UmbrellaException#getCauses
	at com.google.gwt.user.client.ui.AttachDetachException.tryCommand(AttachDetachException.java:87)

        .
        .
        .

        com.google.gwt.core.client.JavaScriptException: (TypeError): $wnd.CKEDITOR is undefined

Any clues why this happens???

Thanks in advance,
Akshay
