I'm trying to do a tree walk and copy with:

<dtml-in objectValues> <dtml-call "REQUEST['where'][-1].manage_addFolder(id)"> Created <dtml-var id> in <dtml-var "REQUEST['where'][-1].id"><BR> <dtml-if "meta_type=='Folder'"> <dtml-call "REQUEST['where'].append(this())"> <dtml-var iterate> <dtml-call "REQUEST['where'].pop()">

....etc...

but I get the following truly horrible error from the manage_addFolder

any ideas?

Error Type: TypeError Error Value: read-only character buffer, Python Method "manage_addFolder" wants to have a string argument (that is what "read-only character buffer" usually means). Instead, it get a "Python Method".

Explanation: "id" is often a method returning a string, not directly a string. Sometimes, i.e. for some classes, it is the string itself. You may use "_['id']". This is equivalent to "id()", if "id" is callable and to "id", if it is not. Dieter
