ConcurrentModificationException when use async
Dear all,
Our team is facing a very strange issue like this:
We defined html dialog with 3 p:remotecommands with **async flag is set to true**.
And occationally we got the ConcurrentModificationException when access to that page. Till now, we didn't find any effective way to reproduce it.
It happens on Ivy Engine version 7.1
May you have a look and support us if you find out something from it.
Thank you so much.
Here is the log. The function loadOpenAmountChart is one of 3 listeners of the remoteCommands
