Hi Bastian,

I am thinking about rendering properties of a certain type (for example 
"string" or "date") with a partial specially for this type. So I would 
have partials for string, integer, date, boolean...
Perhaps ViewHelpers for every type would be better. I still did not 
decide...

A workaround could be this:

class PropertyViewHelper  extends \TYPO3\Fluid\Core\ViewHelper
\AbstractViewHelper {
    
    /**
     * @param void $entity An arbitrary entity
     * @param string $propertyName
     */
    public function render($entity, $propertyName) {
        $getterName = 'get' . ucfirst($propertyName);
        return $entity->$getterName();
    }
}

The basic problem is how to put parameters into a method call in Fluid. 
See Mathias Bolt Lesniak's post "Fluid: condition with arguments" from 
November 3rd 11:30. This is a related topic.

Cheers
Jens
