modules expressions only have already imported modules

[rpatterson]

The modules available in TAL expressions only contain already imported modules while the reference implementation will import modules that aren't yet in sys.modules. Here's the TB I get under Chameleon that I don't get without::

For example, this works fine under chameleon if I just do "import webcouturier.dropdownmenu.utils" sometime before the template is rendered.

Fixed in five.pt trunk (requires currently unreleased Chameleon > 2.2).

Thanks!

I have the latest chameleon from git and it's version is at 2.2 so buildout fails. Can you increment the version?

[malthe]

Done.
