Problem in latest version 4.1.0.62

Hi, I had a project which I developed with version 4.1.0.50. I have been using this version of Essential Diagram. I have customized the Model, View and Controller classes. But today, i downloaded the latest version 4.1.0.62, with this version, I am getting "Object reference not set to instance of an object" exception when i try to initialize the controller with my customized view. The method which i am calling is this.controller.Initialize(this.view); Is there a bug in this method, bcuz i have tested my project with version 4.1.0.50, it is running fine but when i run my project with version 4.1.0.62, it is giving the error which i have specified above. Let me know if this is a bug, some mistake at my end. Regards, Rajesh

Hello Rajesh, I was not able to reproduce the issue that you have mentioned here. I have tested this with the version V4.1.0.62 by creating a small sample and have attached the same here. Kindly look at the attached sample''s CustomDiagram.cs file. Please let me know whether this helps you. If you still run into any problem, could you please modify the sample to reproduce the null reference exception issue. So that it will be easier for us to find out the cause for the problem. Thanks for your interest in Syncfusion products. Regards, Meera.
