I tried to create a skin class in a folder of src of my flex viewer project. I right click mouse, select "New--- MXML Skin", Host component is com.esri.ags.components.Editor, "Create as copy of com.esri.ags.skins.EditorSkin". But it always gives me error message as below:
The source for the skin "{0}" cannot be found
If change the Create as copy of to other things such as "mx.skins.spark.TabSkin", it works. I am very confused about that. Thanks!
