David J. M. Karlsen commented on AXIS2-4534:
--------------------------------------------

I don't see any relation to AXIS-2945  I however have an slightly different usecase.
Given a type someType with an attribute someAttribute where the someType is nillable.
If the element of someType is nil and has an someAttribute value of xyz the attribute won't be retrievable as the the element being the parent is null.

>             Project: Axis2
>          Issue Type: Bug
>          Components: adb
>    Affects Versions: 1.4
>         Environment: Linux, Java 1.5 (I think), Axis2-1.4
>            Reporter: Carsten Sierks
>            Priority: Minor
>
> In a complex element our wsdl states:
> <xs:element maxOccurs="1" minOccurs="1" name="Content" type="xs:base64Binary"/>
> i.e. the element is  not nillable.
> For some reason the user of the service provided it with an empty tag, i.e. <Content/>.
> The result was, that in the method within the skeleton the Content parameter was preset with null, which was not taken into account by the logic.
> I would have expected the deserialisation to throw an error to the service user that an empty tag is not alloved.
