No lock on the Zope3-users list I turn here.
How do I get a page template resource object define in a named layer
from Python code?
Look at what the handler for the <browser:resource> directive does:
zope.app.component.metaconfigure.resource
Thanks Tres,
Already done that. It registers the resource as an adapter on the global
site manger. Problem is I can't get the adapter, but gets an error.
The registration is somewhat strange in it self (adapts from layer
interface to Interface interface???).
I cut and paste my post from the Zope3-users list:
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?
