Feedback on Oblig-I - most will have to resubmit

I plan to send you feedback on Oblig-I by the end of the week. Unfortuantely, most of you will be required to resubmit. The problem is related to the state-machine task. In general, you seem to have problems understading what it means to be reactive, that the machines communicate, and the expected relationship to the lifelines in the sequence diagram. I will therefore focus the first part of tomorrow's lecture on these issues.
