I encountered another problem in SfMaskedInput (it's also reproducable in your samples for this control)
When you type in a value in a SfMaskedEdit control, clear the content (programmatically or by pressing the x inside of the control), then try to enter a new value, the whole app crashes as soon as the first char is about to be inserted in the control.
