Show and Hide with DA.

[robstermn]

I'm trying to hide the scanner_region on form load and then show when a page item is not null . When I implement this option I get the following error when I show the scanner?

Uncaught minimum size of 'config.qrbox' dimension value is 50px.

Hi all, i have also Problem. I want to scan more than 1 Element and i have many Textfields -> when get Fokus i open or hide the APEX QR Code Regions. The first is ok but the second one cant scan (i see the region but not this square for the scan). I tried with setItemValue and Executed Java Script but nothing. Any Ideas?
