I have an ArrayCollection bound to a DataGrid dataProvider, as usual. CollectionChange event is added. When a row is edited and the ItemUpdated() is called, it successfully triggers CollectionChange event if there are less than 9000 elements in ArrayCollection.
But if more than 9000 elements, it will be failed and CollectionChange event will not be fired at all.
Post a simple test case.
Thank Alex for replying. I have created a test and figured out it was my fault. There was a weird "new ArrayCollection" deep inside the code that ate into the CollectionChange added.
