Hello all,
I have a bean of type A which contains a property of type X which is a JaxB
bean (annotated with @XmlRootElement).
I'm editing this being with the help of an Editor<A>.
One of the properties of X is a Boolean which is initialized as
Boolean.FALSE on construction. This property is is annotated with
@XmlElement(required=true).
I do not care about this property in my Editor - it is supposed to be used
only by the back-end. So I don't define any sub-editor to handle it. I just
ignore it.
I use the Editor to create a new instance of A. Both A and X are created
via RequestContext.create().
When I submit my modifications to the server, I have the exception copied
below. I've put a breakpoint on ReflectiveServiceLayer.setProperty, on the
line which calls setter.invoke, and verified that the exception is thrown
precisely when the framework tries to attribute 'null' as value to the
Boolean property which I mentioned above. That property may not be null.
Is this a bug in the framework, or am I doing something wrong? Am I
supposed to create sub-editors for every property of the edited entity?
Here is the exception:
