How to get value for a disabled control?

Hi,
Is there any way to get the value of a control which is disabled on the UI using CAF.model().getValue() method?
I’m using MWS 7.1.3 and i’m unable to get the value whenever i try to do this it throws a javascript error on the UI.

Thanks,
Sravan

When i disable a UI control, it still has a valid CAF.model created for it. Can you attach a sample portlet app please that demonstrates the problem?
