Hi, I managed to install Silva-0.8.6.1 and imported the Silva-0.8.zexp example. As soon as I try to hit the edit-, metadata or access-tab of a document I get the following error. Preview and publish are ok. Can anybody help me out? -- many thanks for your replies, Elena Error Type: AttributeError Error Value: activate_security_hack Zope reported an error for: Path: /silva/publication/fistDocument/edit/tab_edit URL: http://localhost:8080/silva/publication/fistDocument/edit/tab_edit Client: Browser: Mozilla/4.0 (compatible; MSIE 5.5; Windows 98) Remote address: 127.0.0.1 Remote identity: Linked from: http://localhost:8080/silva/publication/edit/add_document File Python expression "model.activate_security_hack()", line 2, in f Traceback (innermost last): File J:\Zope\Zope_2_6\lib\python\ZPublisher\Publish.py, line 150, in publish_module File J:\Zope\Zope_2_6\lib\python\ZPublisher\Publish.py, line 114, in publish File J:\Zope\Zope_2_6\lib\python\Zope\__init__.py, line 171, in zpublisher_exception_hook File J:\Zope\Zope_2_6\lib\python\ZPublisher\Publish.py, line 98, in publish File J:\Zope\Zope_2_6\lib\python\ZPublisher\mapply.py, line 88, in mapply (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\ZPublisher\Publish.py, line 39, in call_object (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\Shared\DC\Scripts\Bindings.py, line 252, in __call__ (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\Shared\DC\Scripts\Bindings.py, line 283, in _bindAndExec (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\Products\PageTemplates\ZopePageTemplate.py, line 228, in _exec (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\Products\PageTemplates\PageTemplate.py, line 95, in pt_render (Object: tab_edit) File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 186, in __call__ File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 230, in interpret File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 689, in do_useMacro File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 230, in interpret File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 712, in do_defineSlot File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 230, in interpret File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 398, in do_optTag_tal File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 380, in no_tag File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 230, in interpret File J:\Zope\Zope_2_6\lib\python\TAL\TALInterpreter.py, line 459, in do_setLocal_tal File J:\Zope\Zope_2_6\lib\python\Products\PageTemplates\TALES.py, line 217, in evaluate File J:\Zope\Zope_2_6\lib\python\Products\PageTemplates\ZRPythonExpr.py, line 48, in __call__ (Info: model.activate_security_hack()) File Python expression "model.activate_security_hack()", line 2, in f AttributeError: (see above) File J:\Zope\Zope_2_6\lib\python\Products\PageTemplates\ZRPythonExpr.py, line 48, in __call__ 44: __traceback_info__ = self.expr 45: code = self._code 46: g = self._bind_used_names(econtext) 47: g.update(self._globals) 48: return eval(code, g, {}) . . . . . g= {'_getattr_': <built-in function guarded_getattr>, '_getitem_': <function guarded_getitem at 00D60A3C>, '__debug__': 1, 'model': <Silva Document instance fistDocument>, '__builtins__': {'cmp': <built-in function cmp>, 'round': <built-in function round>, 'AttributeError': <class exceptions.AttributeE ... 3066 more bytes (not shown) . . . . . code= <code object f at 0364E990, file "Python expression "model.activate_security_hack()"", line 1> 49: 50: class _SecureModuleImporter: 51: __allow_access_to_unprotected_subobjects__ = 1 52: def __getitem__(self, module):
