I need to implement portlet communication between a non HATS portlet and a HATS Portlet. I am using JSR286 Standard portlet.
1. I have a non HATS Portlet which publishes the event
2. I have configured the HATS Portlet to process this event and assign the event Object (payload) to a global Variable by doing the following setting in Project settings
Project Settings > Other > Portlet > Add Global Variable.
I tried to use the above global variable in another screen event to this event value. But I got the below error
Can you please help in understanding the issue here. I do not get a clue here. Please let me if you have any other suggestions in implementing JSR 286 Portlet implementation.
THANKS IN ADVANCE
