Figured this out a while back for the forums, but then promptly forgot and shot myself in the foot.
Consider the following scenario:
- You modify the default site template to have more than one task list – for instance, if you plan to have workflow deployed on the site – which requires a task list.
- You publish a project with that site template.
- You create a schedule for that project.
- The schedule does not appear on the site. You don’t get that cool Project Summary view.
It turns out the schedule is sync’d to the first task list it finds on the site alphabetically. If you have a task list named something like, My Workflow Tasks, the schedule gets sync’d to that list.
The solution is to always make sure the task list that you want to sync with the project comes in first in the alphabet. Optionally, the other method is to modify the Project Summary Webpart so it points to the correct list – although I’d probably check out option #1 first.
