[Zope3-Users] z3c.pagelet, z3c.layer.pagelet and error views not working(Unauthorized)

[Nylan]

Hello, I'm having a serious problem with z3c.pagelet and z3c.layer.pagelet.

I've created my own layer based on IFormLayer,IDivFormLayer,IPageletBrowserLayer.
Layer and skin work fine.
Only with PAU zope doesn't redirect to login page when Unauthorized is thrown. 

Zope always displays:
--------------------------------------
URL: http://localhost:8888/manage.html
Module paste.evalexception.middleware:306 in respond        
.....
Module zope.publisher.publish:130 in publish        
Module zope.publisher.browser:539 in traverse        
Module zope.app.publication.browser:66 in getDefaultTraversal        
Unauthorized: (<z3c.pagelet.zcml.Manage object at 0x22a2f90>, 
'browserDefault','zope.ManageContent')
--------------------------------------

Questions:
1. Why doesn't the redirect in the credentialsplugins challenge work?
2. The redirect doesn't work. 
   Why isn't zope displaying the error view registered for IUnauthorized?



I've found several similar issues:
1.  http://thread.gmane.org/gmane.comp.web.zope.zope3.user/6468/focus=6469
2.  http://thread.gmane.org/gmane.comp.web.zope.zope3.user/7539/focus=7544

I've checked my sources for every hint found above, without
success(z3c.layer.pagelet configure.zcml is included)

Did I include "wrong" packages?

I'll provide information as necessary.

Help greatly appreciated.

Best regards!
