Environment (Required on creation):

• Any setup with Tasklist

Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

• When adding a task comment via the UI, the Java API for retrieving all comments of the corresponding process instance does not return the task comments

Steps to reproduce (Required on creation):

• Create a task comment in tasklist
• Call TaskService#getProcessInstanceComments with the process instance id

Observed Behavior (Required on creation):

• The result is empty

Expected behavior (Required on creation):

• The task should be included

Root Cause (Required on prioritization):

• The underlying REST and Java API for creating comments does not set the process instance id
• This is expected behavior on the API level, however on tasklist level it should be possible to set the process instance id

Solution Ideas (Optional):

• REST API: expose a process instance id parameter when creating a task comment so that the process instance id can be set along with it
• Tasklist: Create a tasklist configuration setting that toggles if task comments are also assigned the process instance id (let's not change the default behavior since using task comments without the process instance id is a valid use case as well)

Hints (Optional):
