it there any technical reason why:

could not return the adapted object based on the context instead of
triggering a traversal error?
Yes. You are not using the path adapter syntax as far as I can see.
You need to have: object/path_adapter_name:function
You should check the parsing implementation (probably some
traversing code) to see about the assumptions.

I know that, I was about to file this as a bug, or write a proposal
to let
tal:define="adapted nocall:object/path_adapter_name"
return the adapted object, but I found a workaround, by adding:
You both are off on the path adapter syntax. The syntax allows
the attribute name to be ommitted. You can write:
tal:define="adapted nocall:object/path_adapter_name:"
(note the trailing colon)
Yes, this is what I tried first (by guessing), but I get a traversal
error unless I write something after the trailing colon
return traversable.traverse(nm, further_path)
File "/home/jmo/Zope3/src/zope/app/container/traversal.py", line 100,
in traverse
raise TraversalError(name)
TraversalError: 'displayable:'
note that the 'IDisplayable' adapter does not implement ITraversable,
but it implements IPathAdapter
class Displayable(object):
"""This adapter makes elements displayable.
"""
implements(IDisplayable, IPathAdapter)
def __init__(self, context):
self.context = context
def getDisplay(...):
...
adapter ZCML declaration:
<adapter
name="displayable"
provides="zope.app.traversing.interfaces.IPathAdapter"
for="..interfaces.IElement"
factory=".Displayable"
/>
so either it is a bug, or am I missing something?
Sounds like a bug.
