Seems that ‘CMaskedTextField’ also does not play well with Mobile browsers. I have a Postal code field that can’t be entered while on most Android and iPhones.
The only thing that seems to make it work is to force the placeholder to and empty character with -
$this->widget('CMaskedTextField', array(
'model' => $model,
'attribute' => 'int_plz',
'mask' => '99999-999',
'charMap' => array('9' =>'[0-9]'),
'placeholder' => '', // makes the field editiable on mobile, but gets the odd moving '-'
));
Which does make it work but the digit sep ‘-’ in the mask moves along as you type which is a bit odd.
Heads up if using the masked fields they have a few gotcha’s
