Hello again! Traceback was missing in the last mail . Used a wrong shortcut und the mail was sent. I try to add an LocalFS Object with an python-product. My code looks like this: from Products.LocalFS.LocalFS import manage_addLocalFS def addLocalFS(self, id, title, basepath, username=None, password=None, REQUEST=None): manage_addLocalFS(self, id, title, basepath, username=None, password=None, REQUEST=None) def manage_addUPortal(self,id,title,base_location,basepath, RESPONSE=None): ... # Add LocalFS addLocalFS(newObj.Linkliste, 'Bilder', 'Bilderordner auf lokalem Filesystem', basepath) What is the error?
