TYPO3.Fluid

I don't think this is a bug. The viewhelper takes the current controller context which is the widget one's. If you need to link to any other controller (e.g. origin request) you have to assign variables for this and submit them in your template.

$this->view->assign('parentPackage', $this->request->getParentRequest()->getControllerPackageKey());
$this->view->assign('parentSubpackage', $this->request->getParentRequest()->getControllerSubpackageKey());
$this->view->assign('parentController', $this->request->getParentRequest()->getControllerName());
$this->view->assign('parentActionName', $this->request->getParentRequest()->getControllerActionName());

In your Fluid template you can do something like this

<f:link.action action="{parentActionName}" controller="{parentController}" package="{parentPackage}" subpackage="{parentSubpackage}">Link</f:link.action>

We have this defined as:
<f:link.action package="xxx.Package" controller="Setup" action="close">close</f:link.action>
And still the link is routed internally in the widget.

Same problem, even with package, subpackage and controller defined the link.action fails to generate the correct link within widgets.

<f:link.action 
    arguments="{account: account}" 
    package="Drinkaccounting" 
    action="show" 
    controller="Account">{account.name}</f:link.action>

http://f3.local/drinkaccounting/controllcenter/index
?--drinkaccounting-viewhelpers-widget-mainnavigationviewhelper[account][__identity]=ec663b7d-04e6-4d9c-8875-eac772f51312
&--drinkaccounting-viewhelpers-widget-mainnavigationviewhelper[@action]=show
&--drinkaccounting-viewhelpers-widget-mainnavigationviewhelper[@controller]=account
&--drinkaccounting-viewhelpers-widget-mainnavigationviewhelper[@package]=drinkaccounting

Also link.action shouldn't generate link to widget actions since there is a viewhelper for that:

<f:uri.widget>
    Generates an URI to another action of the widget.
<f:link.widget>
    Generates a link to another action of the widget.

Any news on this issue ?

Patch does not work anymore in latest Typo3 Flow (1.2 dev-master). This really should be fixed. I currently use the widgets to display a menu with direct access to some objects. That's not an exotic use-case.

Unfortunately I had no success in finding the bug.

After some digging I found another (dirty) workaround for Flow 1.2:

It seems that the problem occurs when the namespaces are added. This somehow has to do with the nesting of the requests and that's why we get wrong links.

If you change in Typo3/Flow/Mvc/UriBuilder.php the function addNamespaceToArguments to this:

protected function addNamespaceToArguments(array $arguments, \TYPO3\Flow\Mvc\RequestInterface $currentRequest) {
        while (!$currentRequest->isMainRequest()) {
            $argumentNamespace = $currentRequest->getArgumentNamespace();
            if ($argumentNamespace !== '') {

                if(strstr($argumentNamespace, 'viewhelpers-widget')) {
                    $arguments["@subpackage"] = NULL;
                    $arguments = $arguments;
                } else {
                    $arguments = array($argumentNamespace => $arguments);
                }
            }
            $currentRequest = $currentRequest->getParentRequest();
        }

        return $arguments;
    }

It works again. This will have some sideeffects if you use links within your widget I think.

But still present in latest Flow version (2.0)

This Behavior is actually no bug, it's by Design.

Widgets are executed in an SubRequest and because of this the URI Builder generates the Link inside that Request.
Currently there is no default way to generate links for another Request.

I'll raise this issue with Sebastian.

Ah, that explains the behavior, would be nice to somehow circumvent it since we have a fluid tag for widget links and one for actions:

<f:uri.widget> / <f:link.widget>
    Generates an URI / link to another action of the widget.
<f:link.action> / <f:uri.action>
    Generates a link / URI to another action.
