Hi, I am doing the following in a PyScript: data = context.session_data_mgr.getSessionData() data.set('upload_ok',1) and I get the following error (w/ traceback) Error Type: UnpickleableError Error Value: Cannot pickle objects Traceback (innermost last): File F:\KANDIN~1\lib\python\ZPublisher\Publish.py, line 150, in publish_module File F:\KANDIN~1\lib\python\ZPublisher\Publish.py, line 114, in publish File F:\KANDIN~1\lib\python\Zope\__init__.py, line 158, in zpublisher_exception_hook (Object: user_views) File F:\KANDIN~1\lib\python\ZPublisher\Publish.py, line 102, in publish File F:\KANDIN~1\lib\python\Zope\__init__.py, line 172, in commit File f:\kandinsky\lib\python\Products\TransactionAgents\__init__.py, line 54, in new_commit File F:\KANDIN~1\lib\python\ZODB\Transaction.py, line 233, in commit File F:\KANDIN~1\lib\python\ZODB\Connection.py, line 345, in commit (Info: (('Products.CoreSessionTracking.SessionData', 'SessionData'), '\x00\x00\x00\x00\x00\x00\x00\x1f', '')) UnpickleableError: (see above) What am I doing wrong?? Is it impossible to do what I want?? If it cant pickle it how is it handling it in when I do CST stuff in DTML?? I cant really move to the default Zope sessions right now because of quite a bit of legacy stuff. Hopefully I will be able to find the time to do it later on.
