Subprocess Signal messes up Data

[kvdinker]

Hi,

Upon further testing with subprocesses, I found an issue with attached signal events. I created a small flow to show the current problem. In our example, we can enter names that are stored in the general instance data or in the sub-process data. However, if we trigger the signal event in our sub-process, the next user task stores the values in our sub-process data and not in the general instance data.

Normal Flow:

Throw Signal Flow:

Thanks
