[Zope-dev] zope.component: calling an Interface and calling queryAdapter give differing results

19 Aug 2008


      From a user's perspective, this makes no sense:
...
...
...
from zope.interface import implements,Interface
from zope.component import queryAdapter
class ISomething(Interface): pass
...
class MyClass: implements(ISomething)
...
m = MyClass()
Right, so this does make sense:
...
...
...
ISomething(m)
<__main__.MyClass instance at 0x00BED6E8>
This does not:
...
...
...
repr(queryAdapter(m,ISomething))
'None'
why the difference?

cheers,

Chris
