If the value to inject does not exist, Seam tries to set the primitive to null. A simple fix might be included in the Reflections.set method: | public static void set(Field field, Object target, Object value) throws Exception | { | if (value == null && field.getClass().isPrimitive()) return; | However, I suppose this does slightly change the injection semantics of stateful components - perhaps the field should be set to the default value for that primitive (i.e. false for boolean, zero for everything else).
