Hi!

I have a DataGrid which dataProvider is an ArrayCollection. I want to bind the collection and the grid. It works fine for adding an removing elements from the collection, but when I modify a porperty within an object from the collection, the grid doesn’t update the changed property.  
Any solution?  
Thx
