I am trying to save some temporary data into the customer session object (
\Magento\Customer\Model\Session ), which I need to retain until a quote is generated. I have tried two methods to save data in session,
$session->setAttValue($value); on a temporary bases. These getter and setter methods reside in a class which I created to handle session related operations and are called from observers.
The problem is : Once I store the value in the session and try to get it back, I am getting NULL value when Full Page Cache is enabled; however if the FPC is not enabled, the accessor method returns expected value from session.
PS: I found an issue which might be similar to what I am facing here, but in the issue, the solution suggested was hole-punching the block, but in my situation, I am not using any block, I am using observers only and I could not find a way to hole-punch function for observer. Any help appreciated.
Thanks in Advance,
