[Zope] Multiple selection property and Zcatalog

[Benoit DOMINIAK]

Hi,
I did a Zclass which has a property called "connection" which I want to be a 
multiple selection property.

How can I access to the value of this property ?
If I put <dtml-var connection> I get a list but I can't access to one of the 
item of the list in particular. I tryed connection[1]... but I only get a 
char : connection is a string !!!

How to index this property in a Zcatalog ?
I want to be able to find an instance by quering on one item of this 
property.

PLEASE HELP...
