Problem with affectation in the "Project" screen

Hello,

I've got a "space case" when I try to affect a ressource in the project screen, when I'm connected with a profile "Team Member" or "Project Leader"



First try

• I'm connected with user with "Team member profile". If I try to insert a new affectation, I have the right screen to do it, I save my input, Projeqtor say me "Affectatoin saved #125" but.......I don't see anything in the scree of th project.
  
• If I connect me as the user concerned by this affectation, he has no affectation on this project.
  
• If I connect me as Admin, it is the same, no affecttion on the project

.

Second try :

• I'm connected with user with "Team member profile".
  
• I affect the ressource on the project with the screen "Affectation" : in this case, it's ok : the affectation appears on the project screen

My question is :

• What is the difference between input an affection directly in the project screen and input the same affectation via the Affectation screen ?
• I think there is probably a problem with right access but where ?

After a few new tests, the situation is already "space"

I already connect me to Projeqtor with a user "Team member" profil (with right to manage affectation)

If I create an affectation via the "Affectation" screen, it works and the affectation appears on the project screen (I knew already)

But what is new :
After this "manipulation", I can create an affectation directly in the project screen
And a problematic "board effect"
If I give to a Team Member user the right to see the "Affectation screen" and the right to create an affectation, he can also add himself as ressource but with a profil of "Administrateur", and then he become Administrateur on the project and can do everything he want

If I disconnect from ProjeqTor and reconnect, I lose this possibility (create directly in the project screen), except if a do the same manipulation described above

Befor, I thought it was a problem of right . But after this new test, I'm not sure.

Can anyone reproduce the same case ?
