When a view behavior is opened it shows a system error "Error determining if a type is a nullable wrapper:Object reference not set to an instance of an object" also it doesn't allow us to delete the behavior |
|
One of the reason this happens is when a behavior has a dynamic view element in the Input or output variable ex:syzDisplayDetail and then the user turns that view element "is dynamic" property to "No" without removing the view element variable in the start shape. To resolve this make sure the "is dynamic property" is set to "Yes". It is always best to avoid this situation by carefully removing the variable before changing the view element property. |
