Persist Many to Many relationship in different steps - php

Question

Hi I try to solve this problem now for days. But I don't get it so I hope you can help me.
I have the entity Worker and it's in a many to many relation ship with the Task entity.
Now I don't want my user to do all input at one time. At first the user should enter his details and if they are valid he can choose his tasks.
So I added three methods to the standard generated code and change the url path in the createAction().
But if I press the submit button in my AddTaskType form there is nothing persisted to the database.
I hope you have suggestions for this problem.
