Put a textareafield under selectfield and datepickerfield like image 1.
Set the focus to textareafield, then close the pop-up soft keyboard, get a blank like image 2.
It looks like the browser didn't properly shift back. What ST2 version?
we use sencha-touch-184.108.40.206.
btw, if we put all selection components under all the textfield&textareafield, it will be ok.
