Hi,

I'm using the virtual list with a filter delegate. The filter uses a 
variable that external to the delegate. When that variable changes, the 
same delegate might return different results, so the list should 
re-evaluate the filter.

Here's a playground example of my question:  http://tinyurl.com/6ywtlw9
The refresh should take place in the button's execute handler.

I would expect to find something like a refresh() method on the list, 
but that doesn't exist. I can accomplish what I want by clearing the 
delegate property on the list, then setting it again to the same 
delegate. This forces the list to refresh. However, I feel like I'm 
missing a more elegant way to do it. Is there?

Regards,
Marc
