The visual editor seems to dislike inner classes.
The VE says “java.lang.IllegalAccessException(Class cuentas.ABM$CampoCod is non-static inner class. These cannot be instantiated at this time.) ” and refuses to show a preview.
The code runs without problems.
I'm using Eclipse SDK 3.5.2 and Visual Editor 1.4.0.
Thanks,
Maria Florencia
