[BUG] ParallelForEach Behavior Inconsistency about elsa-core HOT 2 OPEN

To address the bug report regarding the ParallelForEach behavior inconsistency, it's important to understand that in Elsa Workflow, the ParallelForEach activity is designed to execute each iteration potentially in parallel, depending on the capabilities of the workflow host environment.

From the code segment provided, it appears that the CurrentValue variable is being instantiated within the loop for each item, which should ensure that each iteration has its own isolated context. However, if there are race conditions observed, it could be due to the shared state outside the loop or improper handling of asynchronous operations.

The expected behavior, as mentioned, is correct. Each iteration should indeed have its own isolated context, including its own instance of the CurrentValue variable. If the CurrentValue variable is being shared across iterations, it would be a bug that needs to be addressed.

To resolve this issue, the Elsa Workflow team would need to ensure that each iteration's context is properly isolated and that the CurrentValue variable is not shared between iterations. This might involve reviewing the implementation of the ParallelForEach activity and making necessary changes to the way variables are scoped and managed within the activity.

If you are experiencing this issue with the latest version of Elsa Workflow, I would recommend reporting this issue on the Elsa Workflow GitHub repository, providing the details of the bug, including the code segment, the observed issue, and the expected behavior. The development team can then investigate and provide a fix or guidance on how to avoid such race conditions.

Please let me know if you need further assistance or if there are any specific details you would like to discuss regarding this issue.

@sfmskywalker would you please take a look?
Is there a way to get the CurrentValue in the ParallelForEach without having conflict with other instances?

Thanks.
