[Zope-dev] manage_clone? (amongst others!)

[Chris Withers]

I was going to title this 'I should give up using Zope' but I thought
I'd give it one last go...

Yesterday's 6hrs failing to do a tree-walk-and-copy in DTML failed, so I
thought I'd try in an external method today...

..well, that proved to be just as stupid.

Okay, firstup, has anything happened on this issue:
http://zope.nipltd.com/public/lists/dev-archive.nsf/ByKey/37C533B80F56E22A

Basically, it seems like doing anything with ZClasses in python (an
external method in my case) is likely to lead to suicide on your part.

How shoudl I be instantiating one?

Secondly, AFAIU, the following should copy o and put it in the folder
object 'where' with an id of 'new_id':

where.manage_clone(o,'new_id')

It does, for DTML Methods, but for anything else I get:

Error Type: AttributeError
Error Value: 'None' object has no attribute 'importFile'
(the traceback is in a PS ;-)

Why? How should I be doing this?!

Lastly, in the following:
where.manage_addProduct['OFSP'].manage_addFolder(id,title)

What does the manage_addProduct['OFSP'] actually do?
In what way does the above differ from:
where.manage_addFolder(id,title)

...which works just fine for me...

Hope _someone_ can help,

Chris
