[TYPO3-dev] Parameter in Action does not work for every action

[Xavier Perseguers]

Hi Dirk,

> in my ForumController I have two actions:
> 
>     /**
>      * action list
>      *
>      * @param \DH\Forum\Domain\Model\Forum $forum
>      *
>      * @return void
>      */
>     public function listAction(\DH\Forum\Domain\Model\Forum $forum) {...}

sounds strange to pass an argument of type "Forum" to an action supposed
to lists forums... but that's not the problem.

>     /**
>      * action show
>      *
>      * @param \DH\Forum\Domain\Model\Forum $forum
>      * @return void
>      */
>     public function showAction(\DH\Forum\Domain\Model\Forum $forum) {...}
> 
> in my Forum\list.html I entered
> <f:link.action controller="Forum" action="show" arguments="{forum :
> forum}">{forum.title}</f:link.action>
> 
> (the action used is show or list).

> I get the exception

You did not post the link you defined with action "list". If it exactly
the same as "show", it must work.

Looks like your link is of the form

<f:link.action controller="Forum" action="list">whatever</f:link.action>

of course.

No, just provide the info you need using attribute "arguments".

Kind regards
