[Flow] Remove does not remove

[chris Wolff]

Hi Axel,
to explain it in simple terms
every link triggers a HTTP GET (regadless of the controller or action you call)

most forms trigger a HTTP POST (<form method="post" ..)

the idea is that GET is Read Only and POST is for Writing/Modifing data.

(there are other HTTP Methods but i ommit explaination here to keep it simple)

Most modern HTTP Frameworks Implement such an Architecture know as REST
see wikipeda for more details:
https://en.wikipedia.org/wiki/Representational_state_transfer

as  a GET request should always be "save" so a browser could prefect
the next page you visiting without deleting or modifiing data.

with CSS its possible to style form buttons als links and vice versa.

regards chris
