I$$anonymous$$HO it is bad practice to call the constructor of a SerializedObject (of any non-struct UnityEngine object as a matter of fact). What are you intending to do with it?

I am trying to acces the lightmap setting. I got this code here (my comments in that question) http://answers.unity3d.com/questions/163585/how-can-i-access-lightmapping-settings-for-a-light.html

$$anonymous$$y mistake. SerializedObject is the right thing to use if you wanna access hidden variables through Reflection.

$$anonymous$$y remarks about non-struct object is still right for UnityEngine but not for UnityEditor which SerializedObject belongs to.

Back to your issue:

What is the type of target.dynamicLightsource1? SerializedObject should only be used in editor classes.

Where did you type this line of code? If it is at a class level, note that you should never call constructor on class member declaration.

If you want to access lightmaps, you should use Light$$anonymous$$apSettings.lightmaps wich returns an array of lightmaps used in the current scene.

target.dynamicLightsource1 is dynamicLightsource1 on the target script the editor script is for, its a (point)light. I am changing its lightmapping setting from auto to baked only and that code was the only way I could do it in Unity 3.4

SerializedProperty takes an object (of type Object) as parameter. There is no such property as dynamicLightsource1 in a instance of class Object. Therefore you need to perform a cast first.

Try this solution (here I assume that your script if of type Script):

 var targetDynamicLight : Light = (target as Script).dynamicLightsource1;
 var serialLightSource1 : SerializedObject = new SerializedObject(targetDynamicLight);
 var serialProperty1 : SerializedProperty = serialLightSource1.FindProperty("m_Lightmapping")
