[z3-five] Some problems I found porting Silva views

[Guido Wesdorp]

Hi!

I did some work to get some Silva views to work in Five, and overall I 
was surprised about how easy it was. However, I did run into some 
unexpected problems:

1. in tal there's this repeat thing, which allows to ask properties 
about a certain repeat. For instance, if there's a 'tal:repeat="foo 
bar"' somewhere, you can use 'repeat/foo/number' to get the index of the 
current processing element. These properties, however, are unaccessible 
because there's a Zope 3 security wrapper in the way.

2. A similar problem occurs with the 'modules' element, some Zope 3 
security wrapper prevents it from being usable

3. request.AUTHENTICATED_USER isn't set properly, it returns 
Unauthenticated (or what is it) even though the client has logged in. 
AccessControl.getSecurityManager.getUser() does return the correct user 
object (so that's also a work-around for the problem, perhaps even 
better than using the AUTHENTICATED_USER var).

4. (minor one and discussed by faassen on the channel) form vars aren't 
passed to methods as arguments, so for a request to 
'some_method?foo=bar' some_method is called without the 'foo' argument, 
to get it's value one needs to use something like 'request['foo']'

That's what I ran into so far, I guess more will follow later... I don't 
know if I'm able to fix any of the problems mentioned, I'll have a go at 
it later but I thought it would be wise to report them so that they're 
at least known...

Cheers,

Guido
