i installed two plone 2.5 instances in my window2003 os.all are new,no other tools be installed yet.

but one could install MySite,and another couldn't.

the error info is just as above:AttributeError:manage_addTool.it occured in the method named setupTools,stoped at this sentence:

addTool = self.manage_addProduct['MySite'].manage_addTool

I traced into these two installations,i found that:

One:could install MySite

in Debug Probe,i did this:

>>>p = self.manage_addProduct['MySite']

>>>dir(p)

[Destination, DestinationURL, DestinationURL__roles__, Destination__roles__, __class__, __delattr__, __dict__, __doc__, __getattr__, __getattribute__, __getnewargs__, __getstate__, __hash__, __init__, __module__, __new__, __of__, __reduce__, __reduce_ex__, __repr__, __setattr__, __setstate__, __str__, __weakref__, _d, _getOb, _owner, _product, _setObject, addDeadline, addDeadline__roles__, addOutsourcing, addOutsourcing__roles__, contentinit, contentinit__roles__, factory_type_information, factory_type_information__roles__, manage_addContent, manage_addContentForm, manage_addContentForm__roles__, manage_addContent__roles__, manage_addTool, manage_addToolForm, manage_addToolForm__roles__, manage_addTool__roles__, manage_main, this, this__roles__, toolinit, 'toolinit__roles__']

You can find that there is a method named manage_addTool in it.but for the failed installation.the result of dir(p) is this:

[Destination, DestinationURL, DestinationURL__roles__, Destination__roles__, __class__, __delattr__, __dict__, __doc__, __getattr__, __getattribute__, __getnewargs__, __getstate__, __hash__, __init__, __module__, __new__, __of__, __reduce__, __reduce_ex__, __repr__, __setattr__, __setstate__, __str__, __weakref__, _d, '_getOb']

i don't konw why the manage_addTool method was disapeared.

Note that:all these two installation were new,no other tools,it was a clear plone installation.

Any ideas?

I remember that I would have been hit by the very same problem with the Plone 2.5. But I cannot repeat it anymore. Google reveals that other have been suffering from this too. Maybe you can post the solution here after finding out it?

the very same problem with the Plone 2.5 and zope2.9 , and i try another diffierent os and diffierent version ,but , i have the same errer ,Google or yahoo ,but no one would solution ?why ?who can help to do this /?

i had the very same error today. even more strange: it worked on some machines using the same database and zope-version and on one machine (the production server) it didn't.

here is what id did:

* startup the server in foreground mode

* i found a faulty import in the tools code (i imported
another product that was installed on the test machines, but not on the production server)

* i removed the unneeded import (copy-paste error)

* manage_addTool was available

so setting debug=True in zope.conf or starting up in fg might help you to spot out any incorrect import statements.

Just to confirm that the same manage_addTool error happened to me when I had a faulty import.

I was only able to trace this in debug mode `{client}/bin/zopectl fg debug`

note to self: "always develop in debug mode"
