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
I was able to reproduce the exception that is thrown in the OnPropertyChanged method when the propertyName is null. I've created a support ticket with a reference number of CAS-50654-5600JD so we can research this issue. I will contact you on e-mail when I have more information on this.
Thank you for reporting this issue.
I really need this problem to be solved as soon as possible. Or there will be no way that I can go on using Infragistics :(
It is disappointing when we don't get a reply to our issues. Especially when the issue is related with a dead-end error.
