[Help] Drawing UI of property of object variables property in custom Inspector ?

Hi i am struggling to accomplish the final step which is to draw the UnityEvent myEvent property in the Inspector via the CustomEditor


i figured that it would be much easier to visualize the code i'm working with.

Any ideas on how i can get this working ?

from in the Custom editor i've tried to walk through the code and fetch myEvent like this.

Code (CSharp):

1.   private SerializedProperty mEvent;
2. var index = 2; // lets just get the value at index 2
3. mEvent= serializedObject.FindProperty("ClassBData").FindPropertyRelative("ClassADataset").GetArrayElementAtIndex(index).FindPropertyRelative("myEvent");

but FindPropertyRelative("ClassADataset") throws a null reference exception , i cant figure it out

 

a solution

Code (CSharp):

1.  
2.  private SerializedProperty myprop;
3. private SerializedObject classC;
4.  
5. // whenever we pick a different valie from the ClassA list we set myprop and classC to null
6.  
7. if(classC == null)
8. classC = new SerializedObject(value_FromClassAList);
9.  
10. if(myprop == null)
11. myprop =  classC.FindProperty("myEvent");
12.  
13. classC.Update();
14.  
15. i then say
16.  
17. EditorGUILayout.PropertyField(myprop, new GUIContent("my event"));
