Hey ivan,
Seems like you figured out your initial problem. But here's some advice for your second question.
At the time when you create your task object you can associate it with the relevant Project and the relevant Account (be sure to add these associations in your domain model).
When you then show a list by association to the Project you have known in your dataview (by context) you can use a bit of Xpath to retrieve only the tasks which apply to the current logged in user.
It would look something like this:
Just make sure that you set the association to the project and the account entities when you create the Task object in a microflow.
There are other ways to do this as well.
Hope this helps you get started.
Thanks, this was SUPER helpful and I appreciate the visuals. So I implemented it as you described which makes perfect sense and I havent built the task functionality yet allowing me to add tasks. Once I do I will be able to test that out.
Out of curiosity I originally had an association of task_user. What is the user vs account system members? Just curious as to why we use this one and why it seems there is a bit of redundancy there in terms of functionality.
