[TYPO3-mvc] multiple steps form

[Ismaël Bidau]

Hi,

i'm able to create a fe_user with my form.
After clicking on save, I would like to display a second form. In the 
second one, I need the uid of new fe_user created.

In createAction, I put a redirect('step2'). I would like to had argument 
this new uid but I don't know how ?

Any help really appreciated ;)
