Hi,
I've experienced this issue as well using classes for rendering views when the
class inherits from other class which already have other view declared. For
example:
@view_config( .... )
class myViewClass():
...
@view_config( .... )
class myOtherView(myViewClass):
....
I've workarround it by using more generic meta-classes but it should work,
isn't it?
Greetings,
V.
