Composite Component: SelectOneMenu (enum)

I´m trying to create a simple composite component with a selectOneMenu... It is really simple:


So, the problem is when I´m trying to pass the converter! That is an ENUM converter (extends EnumConverter with @FacesConverter(value = "tipoCampoConverter") annotation)

The error is: javax.el.ELException: Cannot convert tipoCampoConverter of type class java.lang.String to interface javax.faces.convert.Converter

If #{cc.attrs.listValue} is attached to an enum property, it will fail because "selectItems" requires a collection (List or array) of SelectItem, not a single enum, You would have to construct a SelectItem list with a SelectItem entry for each of the enum values that are selectable for this control.


Customer surveys are for companies who didn't pay proper attention to begin with.
 
It is sorta covered in the JavaRanch Style Guide.
