"Value cannot be null." error when PropertyChanged event is invoked with "null" propertyName
posted

Hi,

I've attached a sample project named "ChartError" in order to show the error.

Basically I've a collection of entities that implement INotifyPropertyChanged that is the DataSource of my chart. The BusinesObject layer invokes the PropertyChanged event with "NULL" propertyName when entity changes. But when this happens I get "Value cannot be null. Parameter name: key" error.

Thanks in advance
