Query regarding an error in developer console

[AkashMohapatra]

Hello Sir

I am using Smartclient V10.0 for my project. I am getting a warning in developer console(as below) while loading a window. But, it redirects successfully. I will appreciate if you can throw some light on it. I have the stack trace below for reference.

11:06:06.083:WARN:Log:TypeError: Object doesn't support property or method 'duplicate'
Stack from error.stack:
Canvas.addFieldValidators ()
Canvas.bindToDataSource ()
DynamicForm.setItems ()
DynamicForm.initWidget ()
Canvas.init ()
Class.completeCreation ()
Class.create ()
Global code () @ todo:39:1

This looks like you probably have a set of validators declared on one of your FormItems that you are passing as dynamicForm.fields/items where you have declared "validators" and it's not an Array. It should always be an Array.

Thank you Sir! It worked.
