[Zope3-Users] Making site skins

[Johan Carlsson]

Ok, so far I figured out the following:

1. Resources gets registered as adapters in the Global Site Manager.
2. The adapter is registerd to adapt from the current layer interface 
(defaults to IDefaultBrowserLayer) to the Interface interface (strange, 
why is that so I wounder?)
3. The layer interface I can look up byt calling: 
zapi.getUtility(ILayer, 'my_layer')

Ok, fine. So from my View class I try the following:

         gsm=zapi.getGlobalSiteManager()
         layer = zapi.getUtility(ILayer, 'my_test')
         adapter=gsm.queryAdapter(layer, Interface, 'test_me.html')


But this doesn't work, I get the following error:


Error type: exceptions.KeyError

Can somebody sched a light on this problem?

Johan
