I see this error usually once when I open the first window in my project. I have searched my project and cannot find any occurrence where I might have a color value of ‘-1’. Any ideas as to why this error occurs would be appreciated: WARN [SimpleBoundTagAdapter-AWT-EventQueue-0] Cannot coerce value ‘-1’ into type: class java.awt.Color java.lang.ClassCastException: Cannot

Do you have any color properties bound to a tag?
