MaskedTextBox is throwing an exception when setClearIfNotValid is setted as true

[samuelcardoso]

The exception occurs in:
org.cruxframework.crux.widgets.client.maskedtextbox.MaskedInput.onBlur(BlurEvent)
it's a NPE at textBox field when trying to access it's properties.

A workaround was to avoid appling the mask again after the setClearIfNotValid is setted. So the following code was removed:

if(this.formatter != null && this.formatter instanceof MaskedFormatter)
{
  MaskedFormatter masked = (MaskedFormatter)formatter;
  masked.applyMask(this, clearIfNotValid);
}
