Currently it looks like CollectionView/CompositeView expect itemViewOptions to be declared at definition time rather than instantiation time (ie you can't pass itemViewOptions in when newing up an instance of CollectionView). In every situation where I've needed this capability so far, it's because there's some context information in a parent view that needs to be passed down to the child views at instantiation time. It would be great if itemViewOptions could be specified at that time as well.
makes sense... care to submit a pull request w/ this implemented? should be easy to follow the pattern of other options that work this way. :)
if not, i'll try to get this done in the next few days.
I'll take a stab at it.
The pull request was closed, so this issue should also be closed right?
