Hello, just as I thought that I had understood the acquisition concept (and successfully created some methods that do what I want) I encountered another problem: for testing i have the following infrastructure: /site/programm/index_html /show_vars (DTML Doc.) show_vars: Folder: <dtml-var title><br> <dtml-in "programm.objectValues(['DTML Document'])"> DTML Document: <dtml-var title_or_id><br> </dtml-in> or <dtml-with programm> Folder: <dtml-var title><br> <dtml-in "objectValues(['DTML Document'])"> DTML Document: <dtml-var title_or_id><br> </dtml-in> </dtml-with> now the request "http://localhost:8080/site/show_vars" works but http://localhost:8080/site/programm/show_vars doesn't. I thought that the second request would acquire the namespace of its parents, namely "/site/" and thus be able to find the requested object. (as it does with the "show_vars" object) However I get this error: Error Type: AttributeError Error Value: __call__ ... what am I doing wrong this time? Oliver
