Well but a common use of the viewclass itself is to have methods related 
to "placing pixels on the screen" therefore calling viewmethods its as 
clean as accessing membervariables. Otherwise there is the risk of 
missusing viewHelpers. But as you said trying gives the experience there.

Some words to presentationModel: It has some pros:
*Its a way to get some displaylogic of of the view
* Its a way to save the viewstate independed from the related domainmodel.
* Often the view has diffrent requirements than the related domainmodel: 
So the presentationModel has the missing methods and properties. So 
there is no reason to make the domainmodel "dirty" just because of some 

As I would use it for the blog example:

$postPresentationList is a collection of "postPresentationModels" 
instead of the "post" Domainmodel.


class postPresentationModels
.... public function getSomeFancySpecialTitleForTheWebsite() {
         return $this->post->getTitle().'-Fancy-';

Therefore I would like to call also methods in the template. In this 
case something like:
<f3:for each="{blog.listItems}" as="listItem">

what do you think?
