php - form.post_bind is fired twice -

I added a form event to my symphony form. The problem is that this event is removed twice when I'm debugging, then it goes two times in the method and I do not know why.

I have a form type that uses other form types. I have a VideoFileType form which is adding a field of image type. Both of these forms require some process after submitting the form once.

Image Type

VideoFileType

I do not know why the onPostSetData method is called twice ...
