I have made a product that inherits: "OFS.ObjectManager.ObjectManager" and so should be able to contain other object.

In python any object can be a container, the use of the ObjectManager assists in creating an api and ui for the container's management of objects.

I have given the product a manage option: {'label':'Contents', 'action':'manage_main'} This is inherited from ObjectManager, To make it possible to add content to my product.

But when I add ie. a dtml method to my folderish object, it does it allright, and the document gets added. I know because I can see it directly when going to it's url. And if I try to add another document with the same name I get an error saying that the id is allready used.

But the Item doesn't show up in Itemlist on the "manage_main" page. So I cannot edit the items that I have added.

I only get the: "There are currently no items in XXX"

some more information on what you changed in the container would be useful.

Why is this? is there any special methods or something that I need to create for the Items to show up in "objectItems".

this pseudo code should give you the result you want?, it works for me to display objects in the manage_main. def manage_addMyContainer: foo = MyContainer() bar = MyObject() foo._setObject(bar, 'bar') self._setObject(foo, 'foo') caveat, register your permissions properly on the manage_add, and note that adding bar in this way will mean it won't have access to acquisition properties from further up the tree at creation (including manage_afterAdd). also for registering manage options this syntax is a little more inclusive. manage_options=( OFS.ObjectManager.ObjectManager.manage_options+ ( {'label':'YourTabHere', 'action':'YourMethodHere'}, )+ AccessControl.Role.RoleManager.manage_options+ OFS.SimpleItem.SimpleItem.manage_options ) hth kapil
