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)
