hi I already posted this on monday, but I really don't have a solution yet, so please be patient... The situation is nearly the same as in the CMG(Chapter "Creating a Configuration Interface"), except for the fact that the document to be cloned is not in the current namespace but in some other folder in the zope tree: I want to manage_clone an object into the current folder that lives _somewhere_, let's say in "foo":
/_root |_foo | |_Object | |_bar |_current_folder
there are two DTML-Documents a and b where a is an input form that contains a list of all objects in foo. a calls b. b is supposed to do the following: <!--#call "manage_clone(foo.Object,'new_html',REQUEST)"-->
try something like
<!--#call "manage_clone(_.getitem(foo,Object),'new_html', REQUEST)" --
where Object is the value from the form.
o.k., the form field is named "input", so I tried: ..._clone(_.getitem(foo.input),...) => Attribute error, error value input
or even: ..._clone(_.getitem(_.string.join(['foo',REQUEST['input']],'.')) => produces the correct ID "foo.Object", but produces a key error...
so I tried to test a hardcoded name in getitem() and put this into the code: ..._clone(_.getitem('foo.thename',0),... where 'thename' is an existing ID in the folder foo => key error. I think getitem() somehow cannot handle the object path. I didn't even find the place in the source where getitem() is defined The problem is that my application relies on this. I can't proceed... :-(
One more shot in the dark (I recall trying just about every conceivable variation, but can't remember which worked): have you tried _clone(_.getitem(foo, REQUEST['input']) ???
well, yes. It gives me: ->Error Type: SystemError ->Error Value: bad argument to internal function I think the problem is that getitem() accepts only two arguments, the second of which is a flag of 0 or 1, whereas in your example it would be a string. I'm really a little annoyed... actually, this is a very simple task, but I don't get it. I just tried to workaround it with manage_copyObjects() and manage_pasteObjects()... (not very smooth), but I get an error, too:
The data in the clipboard could not be read, possibly due to cookie data being truncated by your web browser. Try copying fewer objects.
Maybe someone from Digital Creations have an idea? Heiko. -- Heiko Stoermer MIG Augsburg
