ConcurrentModificationException on asynchronous data page load
Concurrent Modification exception occurs when the system loads a data page asynchronously.
Steps to Reproduce
- Create a parameterized requestor level data page. In the load activity, refer another requestor level data page.
- Trigger a data page to load asynchronously.
A node level data page expands by invoking the expand(true, true). However, this does not expand the PropertyStreams. As a result, the exception occurs while expanding the PropertyStreams when two PRThreads copy from the same node level page.
