New submission from do3cc <do3cc...@googlemail.com>: This occurs in plone, after changing the Missing class to at least provide the __class__ attribute.

This very basic extension class has no __class__ attribute. I added it in a branch of the 'Missing' package. In 06 and 10 it starts doing some wrong assumptions for our case, and tries to translate the missing value. Translation throws an Unhashable Exception, because the 'Missing' object is not hashable. Gettext requires hashable msgids The attached patch provides a test case that triggers the described behaviour. ---------- messages: 415 nosy: do3cc priority: bug status: unread title: Chameleon treats every non simple object as a msgid. Non hashable objects will throw exceptions when being used as msg ids __________________________________ Repoze Bugs <b...@bugs.repoze.org> <http://bugs.repoze.org/issue150> __________________________________ _______________________________________________ Repoze-dev mailing list Repoze-dev@lists.repoze.org http://lists.repoze.org/listinfo/repoze-dev
