$_format is lost on failure_forward

[mvrhov]

I've been debugging this for the past few days but to no avail.

This is the excerpt from my security file:

security:
    firewalls:
        default_json:
            poshtar_login:
                login_path: /login.json
                check_path: /login.json
                failure_forward: true
            context: store
            anonymous:  ~
            logout:     { path: /logout }
            pattern:    /.*
            provider:   poshtar

What I was able to figure out using a debugger is that the content type for subresponse? is set correctly to json, but sometime later, when responses get merged? and the request is asked again for a format the request returns html as the attributes bag is empty (controller resolver set the proper format in subrequest) so data sent to the browser has a wrong content type.

@mvrhov did #3564 fix your issue ?

Can you give me a couple of days to confirm. I have to update an app using ~one year old experimental forms branch, which is also using custom auth providers.

I still haven't had the time to fully update my code to be able confirm this.

Task for the BHD: check if this issue still exists in 2.0 / 2.1

@vicb: aa53b88 (i.e. the #3564 fix) did not fix the issue, but 347053c did; therefore the issue exists in v2.0.15 but not in v2.1.0-BETA1. A test case is available at https://gist.github.com/3007325

@vicb This issue is fixed then?

Closing this issue as it is fixed in master.
