[Flow] identifier gets lost in form

[Winfried Mingst]

Hi Alexander,

I debuged "detail" before and after a validation error in edit form. 
I'm on latest 2.0 dev-master.
 
initial detail:  
http://666kb.com/i/cfdxxs0ydkfnkam2v.jpg

after form is reloaded: 
http://666kb.com/i/cfdxyx7w8ilx14j0n.jpg

hidden field for master has disapeared
{detail->f:debug()} still holds the right identifier. But afer submission a
new master record is created an associated with detail.

DetailController.php

Cheers

Winfried

Hi Winfried,

some things I notice in your code:

1. newAction does not have the Detail object as optional parameter,
hence when there are validation errors in createAction, all input will
be lost because the invalidated object isn't provided to the template

2. editAction (and newAction after following 1.) should add
@Flow\IgnoreValidation("$detail") annotation, so that validation errors
don't create an infinite redirect

Regarding your problem with the missing master __identity after
validation errors however, I can not see any obvious error.
It *could* be a bug in Flow/Fluid, best would be some debugging on what
happens with the Detail object in editAction when an validation error
occured, so maybe you could do some debug output if the master property
is still correctly set. If it is, then it's maybe a problem with the
form viewhelper.
Would be good if you could then also provide information on what version
you're currently on (master/1.x/2.0).

Regards,
Alexander
