Hi, You can't do what you are trying to do here. The factory-method needs to return an object that represents the bean. In this case it returns void. It is not a very nice error, we shouldn't throw a NullPointerException.
In this scenario you are defining a bean without providing an instance that could back that bean. Alasdair 2011/2/22 Łukasz Dywicki <l...@code-house.org>: > Hello, > I have small problem with Aries.
