What is best way to link two interactive reports?

Question

Hi,
=================
Basic Set UP
=================
I've created two interactive reports-- Project report in Project page and Task report in Task page.
Project report in Project page can contain multiple projects.
Task report in Task page can contain multiple tasks.
One project can have multiple tasks.
But one task can have only one project.
=================
What I'm trying to achieve
=================
When I click a Project Name, it should pass Project ID to Task page and display tasks that are pertaining to the project.
When I create a new task, the passed Project ID should be mapped to the task.
=================
Challenges
=================
1. How can I pass Project ID from Project page to Task page while clicking Project Name in Project page ?
2. How can I get Project Name in Task page based on the Project ID passed from Project page ?
3. How can I display tasks pertaining to the Project Name ?
4. How can I take Project ID passed to Task page and map it to a new task?
Thanks,
Guy

1. How can I pass Project ID from Project page to Task page while clicking Project Name in Project page ?Create hidden item in Task Page, for example :P2_PROJECT_ID. Than link on required column to Task page:
Interactive Report -> Edit Column -> Link.
2. How can I get Project Name in Task page based on the Project ID passed from Project page ? There is two ways you can create a function that will return project name by id or you can post project name to task page (The second way is unsafe, you can miss some parts of your project name if you will have a ',' symbol)
3. How can I display tasks pertaining to the Project Name ?In interactive report source add condition to your query, for example:
and task_table.project_id=:P2_PROJECT_ID
