It seems normal

Yes of course, I say that because I check it before.
If validation fails, none of form_alter, validate or submit (this is logical not call submit if validate fails) are called.

_validate function isn't called, if I add this in _after_build function, it doesn't change anything, a call to form_builder in
this _after_build doesn't change anything (changes are made but not transmitted to drupal_render).

It was set ;-) (see above)

My pb is why my modified form (in _after_build, I'm sure, diplaying its dump with drupal_set_message) isn't transmitted to
drupal_render ?

And I don't understand why drupal render is called twice with this form (same form_build_id)...

Thanks for suggestions

(I'll look what happen with a standard nodetype as page to better understand fapi process)
