there might be some technical limitation on the Adobe QRCode control. As currently the ADS in my server is

down, I could not do more testing on it. I suggest you create an internal ticket to CSS component XX-PART-

ADB-IFM also write mails to the responsible colleagues there. They have enough expertise to help you.

 

Best regards,

Jerry

Hi Jerry,

 

This was an awesome tutorial. This helped a lot. Thanks for sharing this. There seems to be a small problem

with this, when I am trying to generate QR codes for URLs which has lengthy strings ( i.e more that 155 chars),

QR code is not generated. Is there a way by which we can resolve this issue?

 

Regards,

Riswan
