FlowJoin Activity Triggering Next Step Twice with WaitAny / WaitAll

[sagargolu]

@sfmskywalker ,

We are currently using the main branch with the last commit "e618190" but we're encountering an unusual issue when working with the FlowJoin activity.

As shown in the attached screenshots, we have configured the FlowJoin activity with the WaitAll option. The problem arises when we attempt to complete two sub-workflows, [Main Test SubProcess 1.2] and [Main Test SubProcess 1.3]. While the activity correctly waits for both sub-workflows to finish execution, the subsequent activity is triggered twice after both have completed. The same is happening with "WaitAny" as well.

We are seeking your assistance as we cannot pull the entire latest code into our branch at this time to resolve the issue. Your help in identifying the specific fixes needed would be greatly appreciated. Could you please let us know the commit numbers we need to pull to address this problem?

I'll take a look.

I tried reproducing this with the latest source code using the attached workflows, and it works without issue. I assume therefore that the issue doesn't exist in the latest version.

It's tricky to find the exact set of commits you'd need to pull in, but perhaps you can just take the contents from the following files, instead:

• https://github.com/elsa-workflows/elsa-core/blob/main/src/modules/Elsa.Workflows.Core/Activities/Flowchart/Activities/Flowchart.cs
• https://github.com/elsa-workflows/elsa-core/blob/main/src/modules/Elsa.Workflows.Core/Activities/Flowchart/Activities/FlowJoin.cs
• https://github.com/elsa-workflows/elsa-core/blob/main/src/modules/Elsa.Workflows.Core/Activities/Flowchart/Models/FlowScope.cs

Now, it's possible that additional changes were made that lead to the resolution of the issue you're seeing, but this would potentially require a significant amount of time to figure out. If updating the above files doesn't work, then you might try and update the entire Elsa.Workflows.Core and Elsa.Workflows.Management projects and files.
