i actually have a Problem with restrictedTraverse and hasattr.

Object1 Object2 Object3

I want to test if there exists a Object in Object3 wich has the same id and meta type how Object2 (id=myobject). so i ask

Object3.restrictedTraverse('myobject',None) or

hasattr(Object3,'myobject')

i every time get's true back.

You can write a Script(Python) "hasattr_unacquired" with parameters "obj, attr" and body return hasattr(obj.aq_inner.aq_explicit, attr) Note that a solution without the "aq_inner" will often work but is not reliable... -- Dieter
