hi again ... i would like to know, how it would be possible, to reverse the function of the TransparentFolders, because i wan't to use them as a patch-like function to existing zope trees. Scenario: You have a Zope Application, that uses more than 1000 objects in the zope tree (e.g. /main) which you did sell to many customers. Every customer also had the choice to get some minor modifications to this main tree. Now I thought i could have the main tree, and use the TransparentFolders to FIRST look into these, and after not finding anything in them try the main tree. You could have a set of Folders as incremental updates to the main tree that are a bit more "atomic". Any hints? At most, i require more information of the process of finding an object, to know where to threshold the alternative search procedure. Tnx and good night.
