I am unable to change View of MultiView when I use two RequiredFieldValidator in single view.

Two RequiredFieldValidator operate on a TextBox and a DropDownList, it doesn't show validation error when I fill them, but doesn't also let me move from one view to another. When I remove Cascading control and assign any other text to DropDownList via ListItem, it works properly. I thought MultiView has problems with more than one RequiredFieldValidators so i tried using just one on DropDownList and that failed as well. It works when I remove CascadingDropDown extender or RequiredFieldValidator for DropDownList.
