[Grok-dev] "Apply" a pagetemplate to an object and get html back

[Achim Domma]

Hi,

how do I apply a template to an object an get the html code back? To  
learn grok, I'm developing some kind of yet-another-mini-cms. I want  
to let the user edit the page body via a webform using textile or  
markdown for example. Then I would provide tags to display some kind  
of specialized lists like "events", "links", ...

How do I do that using grok? Or is there a better approach to solve  
my problem?

regards,
Achim
