I think that topic was raised before, but I can't find any information about what's going to be done on that :) The zope.app.publication.traversers.SimpleComponent (that's used by default for most of objects) in its publishTraverse method uses the adapter lookup without asking for some specific view interface (like IBrowserView), like this: view = queryMultiAdapter((ob, request), name=name) This causes problems when we have any non-view context/request adapters registered. One real-life example of that kind of adapter is ILayoutTemplate adapter registered with z3c:layout directive from z3c.template package. So the publisher that looks for views should look them up like this: view = queryMultiAdapter((ob, request), IBrowserView, name=name) One issue is that SimpleComponentTraverser also provides IXMLRPCPublisher and (as far as I understood) should be able to look up IXMLRPCView adapters. I'm asking about how to fix this without breaking much backward-compatibility. Should we just write split the traverser in two (one for IBrowserViews and one for IXMLRPCViews) or should we look up the view depending on request by using if/then condition (if IBrowserRequest is provided - lookup IBrowserView, if IXMLRPCRequest provided - lookup IXMLRPCView). Or probably some other way? Also, is there any things to note when fixing that issue? Thanks in advance for any comments on this. -- WBR, Dan Korostelev
