So zapi.getMultiAdapter creates the view, but how can I initialize it with it's required parameters (context and request) ? getMultiAdapter does that. I speak from personal experience. Whoops ! I'm really sorry but I think I made a stupid mistake in my zapi.getMultiAdapter() call, because I used a custom request as parameter instead of the initial request I received in my JSON MethodPublisher subclass ; that's probably because of several tests I made to get things working as I need... :-( Really sorry again, but now it works perfectly...

[Zope3-Users] Getting view result from Python
Hi, I'd like to get a view output from some Python code. Actually, I don't have any problem if I use a page template with a simple tal:x content=structure context/@@viewname / expression and return self.template() in Python. But it should certainly be cleaner and less expensive to get view output directly from Python code, which I don't actually manage to do... So any advise to this probably simple problem would be welcome.
