You will need to debug this, figure out which line is throwing this exception and review the code. If you don't see what is going on, please paste a snippet in here for further comment.

Mulitiple change listner is occur most of the time just because of, we were trying to set same listner again and again
Try following piece of code, it will throw IllegalStateException: Multiple change listner not allowed
ButtonField btnClick = new ButtonField("Click Me");
//here I can assign listner two times to same field
