Hello Zopistas, as I was just testing moving a big, old application to Zope 2.13, I was greeted with the following error: (...) from Products.ZCatalog.CatalogPathAwareness import CatalogPathAware ImportError: cannot import name CatalogPathAware Looking at the code informs me that CatalogPathAwareness is deprecated, but wouldn't that mean that it should still be there? Next part of the question: Looking at http://pypi.python.org/pypi/zope.lifecycleevent I see some examples about calling those notify() events, but nothing that would tell me how to replace CatalogPathAware with this stuff. Googling for [CatalogPathAware zope.lifecycleevent] does not give me anything besides some SVN commit messages. So, anybody have some examples of doing this? Specifically an example for replacing CatalogPathAware with zope.lifecycleevent. Since this is what the depreciation message talks about, it's been done many times over and should be well documented, right? I also hope that developers are aware that this change involves changing the base classes that classes in production systems out there are based on. Thank you very much, Regards, Sascha
