I don't see anything that is related to my code in the log displayed. Can anyone help on this issue? Thank you in advance... Reproducible: Always
If I can't reproduce it, I can't comment on it. Most likely you're doing something funky in your model's implementation classes that I'd need to see. If you can provide a reproducible test case, please reopen it.
Created attachment 189470 [details] File which throws the ConcurrentModificationException In the Attached file,the exception is thrown inside the method LoadRepository(). While debugging,Found that its thrown at the first line of for(MSkeleton skeleton : getSortedSkeletonList(skeletons)){ } how to make changes so that this ConcurrentModificationException does not occurs?
