[Zope] create folder within folder-object via DTML

[Ingo Assenmacher]

Hi all!

I want to automatically create some instances of default objects whenever
creating a specific folder-object within the zope-management interface.
This is what I do within the constructor of a folderish object:

<dtml-with "termin.createInObjectManager(REQUEST['id'], REQUEST)">

<dtml-call "manage_addFile('invitation', '', 'Einladung')"> // (works)
<dtml-call "manage_addFile('protokoll', '','Protokoll')"> // (works)

 <dtml-call "REQUEST.set('id', 'material')">
 <dtml-call "REQUEST.set('public_view', '1')">
 <dtml-call "REQUEST.set('public_upload', '0')">
 <dtml-call "REQUEST.set('owner_delete', '1')">
 <dtml-call "REQUEST.set('store_in_db', '1')">
 <dtml-call "MaterialFolder_add(_.None, _, NoRedir=1)">

The last one works, too, BUT the folder is NOT created within the folderish
"termin" (unlike the "add_files").

This is what I want:

termin (folder)
 | invitation (file)
 | protokoll (file) 
 | material (folder)

And this is waht I get:

termin (folder)
 | invitation (file)
 | protokoll (file)
material (folder)

How is this?
 Thanks for any help!

Regards, Ingo
