How does this work when using future anterieur

Question

I understand the lesson as it is taught above.

In the lesson for future antérieur (Conjugate vouloir/pouvoir/devoir in the future perfect in French (Le Futur Antérieur)) there are sentences like "Nous aurons voulu le revoir". Why not Nous le aurons voulu revoir?

Is there another rule applicable when using future antérieur?

Accepted Answer

Fzum,
This word order is not determined by the tense/mood, and there isn’t a special rule for this construction with future anterior.
When there is a construction (in any tense/mood) with ‘conjugated verb - infinitive’, the object goes directly before the infinitive. 
The object is not placed before the conjugated verb in such sentences and therefore ‘Nous le aurons voulu revoir’ is not grammatically correct.
