[Flow] How to build a search/filter form above of a list

[Axel Wüstemann]

Hello,

how I can build a search form above of a list. Forms need to contain 
object, but here I don't have an object, I have several fields by which 
I want to filter my list.


I tried:

<f:form method="post" action="index" object="{filter}" 
objectName="filter" enctype="multipart/form-data">
...

And in my indexAction

public function indexAction(array $filter = null) {
   ...
   $this->view->assign('filter', $filter);
		
   // the options for lookup selectbox
   $this->view->assign('fasts', 
$this->lookupRepository->findAllActiveFastsAsOptions());
}


Within my filter fields, I have selectbox 'fasts' which I initialize 
with options. On submit of the search form, only this select box is set 
in the $filter array, not other fields of the form, not the other fields 
I filled.

How could I solve this?

Thank you
Axel
