I'm trying to write a XPObject that should always be bound to a criteria that is user dependent. I don't want to place this criteria  everytime I make an XPcollection.

So I was hoping I could add it to the XPObject itself.  Is this possible ?

Might need a bit more information,

Are you trying to implement a security type system whereby only a collection of objects are returned based on that user?

If so you will probably be best just writing a small helper class.

What criteria are you wanting to apply to the collection?

I'm developing an application that should work for 3 countries. Netherland/Belgium/Luxemburg.

The 3 counties should  have a few tables with shared data. And a few with data that only the specified country (specified in the user table) should see.

I know I can just place a criteria on an XPCollection but I was wondering if I could place it in the XPObject itself.
