When you click the remove link in a report for OneToManyComponent, the
element is removed from the report but is still in the memory. Here are
steps to reproduce :
Open :
http://localhost:8080/seaside/examplebrowser
Click Edit
In 'Phone numbers' click Add
Put values inside fields and Save
Give a first name and a last name
Save the form
Remove the phone number
Click Edit
In 'Phone numbers' click Add
Put values inside fields and Save
The two phone numbers are displayed even if we removed one.
