Hey Tom, In response to this question and the BindingUtils and ArrayCollection.filter question, I offer this suggestion. In the ModelLocator maintain a single master Array of all the users. Then in each instance of your view components, create a new bound ArrayCollection (dataProvider), with the master Array as the underlying source. Each of the ArrayCollections will have a different filterFunction based on the type of view component that is instantiated. Because the ArrayCollections don't actually contain any data, just pointers to the underlying Array, I would handle the ArrayCollections and filterFunctions in viewHelpers. In a sense, you would be creating separate sub-sets of the master Array in each instance of your views. If you preferred, you could maintain each ArrayCollection (Array of ArrayCollections) in the ModelLocator as well.
I hope that this makes sense, Tim Hoff --- In [email protected], "Tom Bray" <[EMAIL PROTECTED]> wrote: > > Say my model has an ArrayCollection of all the users that are > connected to my Flex app. I then have configurable list views that > display different subsets of that collection based on different user > properties (gender, age, location, etc.).
