1. Click the button "new"
2. Review all text fields on the window ("First name", "Last name", "birthday", "e-mail", "Password", "Student No")
3. Fill the gaps "First name", "birthday", "e-mail", "Password", "Student No" using numbers and letters
4. Click "create"
Expected result :
The window "create new student" must show "please provide Last name"
Actual result:
The window "create new student" is closed. This window has to be opened one more time that to show "please provide Last name"
P.s.
This bug applies to the fields "First name", "E-mai", "Password" and to the tab "teachers" in the same fields.
