Don’t import inside of PyObjC actions

Bob Ippolito came to my rescue today. I started using Cheetah for some template work, and it turns out that doing:

from Cheetah.Template import Template

from within your action is bad. (Bus Error bad, not simple exception bad.) So, if you’re using PyObjC, make sure you do your imports at the module level, not in a given block of code.

Update: Bob tracked it down. Don’t import Cheetah inside of an action, because it will import PyObjC’s WebKit (thinking that it’s getting WebWare’s WebKit) and importing PyObjC’s WebKit inside of an action has some issue at present. So, go ahead and do imports wherever you want again, as long as it doesn’t involve WebKit 🙂
