Re: [Zope] AttributeError on SESSION

Are you perhaps trying to do session ['last view'] somewhere else without checking that it first exists? The reported problem looks as if the REQUEST were used after it has been closed. This can for example happen when an acquisition wrapper is cached in a _v_ variable. The wrapper has at its bottom a stale REQUEST object, now closed. A closed REQUEST has lost all content of its other, among them SESSION. -- Dieter ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

This works as advertised in my other instance but throws the same

everything I found assumed that SESSION was working :)

Re: [Zope] AttributeError on SESSION
Are cookies enabled? If not, should be. Yes. I should also note that I've tried this on two different machines (connecting to both instances). what does request look like dtml-var REQUEST Is SESSION presnt? Well, on the good Zope instance the first few lines of REQUEST look pretty good: form cookies tree-s 'eJzTyCkw5NLIKTDiClZ3hANXW3WuAmOuxEQ9AIOOB9Q' __cp 'x%DA%D3%60b%60%60%C8%04b%86hF%20%A1%01%E2%16%83%B8%C5%3C%40%22%3F%AF%24%DF-55%25%2919%1B%00W%E7%06%D1' _ZopeId '07894127A2QSmdNEV4g' lazy items SESSION bound method SessionDataManager.getSessionData of SessionDataManager at /session_data_manager But on the broken one I get: form -C '' cookies tree-s 'eJzTyCkw5NLIKTDiClZ3hANXW3WuAmOuxEQ9AIOOB9Q' __cp 'x%DA%D3%60b%60%60%C8%04b%86hF%20%A1%C1%0C%24J%40%DCb6%20%91%9F%1A%92Z%5CR%C2%0Dd%26%A6%A4%B8%A5%A6%A6%24%25%26g%03%00%9C%D2%09%29' lazy items Note that the broken instance (I'll call it 'b' and the good one 'a') also has /session_data_manager and it is configured identically to the one on A. Also, the last time I used something SESSION based it was working (which is why I figure that I've managed to hose something up along the way). ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
