Application hangs when closing multiple message notification

Application hangs when closing multiple message notification

Content

Hi,

Use case - I am calling 4 action chains in parallel mode in vbenter. Each action chain has a Rest call to get some data. In case rest call fails, I am firing a notification in each action chain. The problem is when user gets 4 error notifications and tries to close it, application hangs.Even VBCS development environment becomes unresponsive.

The issue seems to be with parallel call.

The issue seems to be with parallel call. I saw the console and found out when we are trying to mutate  in built messageADP in shell page, messageADP is having issues in finding the key of the closed message notification if they are fired from action chains called in Parallel flow.
