[Zope] not to acquire from parent

[Service Informatique CHSR]

Hello,

I trashed my archives, and I can't manage to remember this.
If someone could remind me this one...

How can I test if an object is not acquired?
I guess I have to test the existence of the object in aq_base.

<!--#with aq_base--><!--#if object-->
...
<!--#/if--><!--#/with-->

hangs.

<!--#if "_.hasattr(PARENTS[0].aq_base, 'object')"-->

is always false.

Any other idea?
