Present Perfect vs Present Simple in time-clauses

[sergeyrais]

What's the right way to use durative verbs in a time-clause?

I shall go for a walk when I do my homework.
I shall go for a walk when I have done my homework.

Are both variants possible?

I'd use 'I shall go for a walk after I have done my homework' though the second sentence sounds possible to me. The first one doesn't work for me.

The first one is incorrect.

Taking into consideration the durative aspect of the verb do in the phrase do one's homework can we refer the two actions (going for a walk and doing my homework) in the sentence "I shall go for a walk when I do my homework" to the same time?

I shall go for a walk when I do my homework = (?) I shall be walking and doing my homework.​

Yes, but it's not a natural way to say it. It would be more natural as "I'll do my homework while I'm walking".
