Bug - SfScheduler causes a null reference exception when accessing CSLA managed properties

[Lee Stevens]

Hi,

As the subject suggests there is an issue accessing managed properties in the SfScheduler. I have attached an example with 4 scenarios accessing the same business list object:

• Basic text list
• SfScheduler
• SfGrid
• SfScheduler (Without managed property)

Only the SfScheduler accessing a managed property causes the issue, I have only tried this with SfScheduler and SfGrid but grid seems fine. 

The property being accessed is RecurrenceID, I have also seen the error occur with RecurrenceException either set to null or an empty string.

Look forward to your solution.

Hi Lee,

 

Sorry for the delay,

 

Due to the complexity of the issue, we need additional time to validate the reported issue at our source end. So, we will check and update it by Monday, June 5, 2023. Appreciate your patience until then.

Hi Lee,

Sorry for the Delay.

We had checked your query at our end. The issue with managed properties were caused because, we had processed each occurrence appointments using Activator.CreateInsance from the parent recurrence appointment at our source end. Since in CSLA 6, Activator.CreateInstance will create this runtime exceptions and the same works fine in CSLA 5. We prepared a sample for your reference in CSLA 5. To resolve the issue in CSLA 6, we suggest you to define the Appointment model class without managed properties.

You can find more details about this exception in below link:

Hi Mugilraj, 

Thanks for your detailed response. I have removed the backing fields and that seems to work with the calendar now. Are there any other Syncfusion components that function in a similar way? For example, we never had the problem with the SfGrid when using the same business object.

Thanks, Lee.

Hi Lee,

We have checked your reported query and let you know that SfGrid will not have the problem with the initial load. But, same problem will occur when you perform editing in SfGrid.

Please let us know if you need any further assistance.
