I have an interface with 4 labels, 4 textfields and some buttons like "Add", "modify, "next", etc. The user will enter name, first name, birth date, etc. After clicking the button "add", the information that he has entered will be added on rdf file. The "next" (in french "Suivant") button didn't work. When i click on "next" button, nothing appears on textfields. There is nothing in the textfields.
Can you tell me what's wrong?
Thanks.
