[TYPO3-mvc] Blog example: Number of comments

[Sebastian KurfŸürst]

Hi Julian,

in your context, it makes more sense to use a variable.

RenderChildren should mainly be used if you need some text content which 
you process somehow.

Thus, in your case, I'd rewrite the ViewHelper to have <NAMESPACE:count 
array="{post.comments}" />.

Then, you'll have strong type checking and all this as well :-) and the 
performance is a little bit faster than with using sub nodes (though 
this is neglectible)

Greets,
Sebastian
