[Zope] ZClass > Multiple inheritance > "Empty" Folders

[Célio Conort]

Hi !
here's my problem :
i've got one zClass : baseCard which have 4 propertyshets and methods ... it
just inherits from zObjects, and CatalogAware
and then i'm trying to create a new zClass specialCardFolder which inherits
from baseCard AND OFS : Folder (i just want a folder with the same
properties myCard's has)
So my new specialCardFolder is working fine, i can edit it's properties, i
can add subObjects ... but can't view them !
the sub objects are created i can edit them via
/mySpecialFolder/objectX/manage_main but mySpecialFolder/manage_main keep
saying : No Items !
i wrote a method content which lists objectsIds (or objectsItems) but it
keep saying it's empty !
and if i create a zCatalog and tell him to find all the objectX in my
website, ... he can't find thoose objects in mySpecialCardFolder ....

any idea ??
thanks a lot !
