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 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.
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.
Just to let you know that the service release that includes the fix of this issue is now available from our website.
Let us know if you need further assistance.
Thanks but we are using IdeaBlade's DevForce on the backend so we are not the ones raising PropertyChanged with NULL value. Therefore I need the fix ASAP.
I leave the issue number here (#36554) in case anyone encounters this and wants to subscribe for status updates
I will enter this issue in our system so it can be evaluated by our developers. In the meantime, you may use String.Empty instead of null value in the NotifyEntityChanged() method.
Thanks!
