I can't get Mylyn to save current context using pydev

问题

I'm starting using eclipse with PyDev, and I want to use Mylyn.

However, when I'm working on an active task, Mylyn is not saving the opened files in context. I press right button on my active task, go to "context" option, and I noticed every option is disabled.

Any clue?
