I found in windows mobile device,I found a strange issue in Barcode API:
if fist call
Barcode.take() or Barcode.enable
Then I found the Barcode will never launched, it will only works if I just call render method, like
render :action =>:index
Did anyone find the similar issue, or is it a known issue?
It is currently by design that navigating away from your current page will disable the barcode scanner, it is recommended to only enable and configure the scanner on those pages where you will be doing scanning.
