Ok, maybe if you can provide some sample code or a
screenshot of what these two views look like would help. Is it that the two
views are going to update the data in two different
fashions?

Subject: [flexcoders] Re: Cairngorm microarchitecture. 2 instances of view with different data.
I have
1. 2 different set of delegates (different classes)
2. 2 different data instances (the same data class)
3. 2 instances of ONE view that support 2 modes.
I have to see in THE SAME TIME one instance of view with one set of
data and another with second set of data.
Waiting for reply.

on our 2 views. First part done.
