> CXF Extension bit @QueryParam("") does not allow null values in the bean
> ------------------------------------------------------------------------
>
> Key: CXF-2787
> URL: https://issues.apache.org/jira/browse/CXF-2787
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 2.2.5
> Reporter: Matt Inger
> Assignee: Sergey Beryozkin
> Fix For: 2.3, 2.2.8
>
>
> If you use the @QueryParam("") extension bit on a method parameter:
> {code}
> public void foo(@QueryParam("") Bar bar);
> {code}
> you cannot have fields in the Bar class with null values. The problem stems
> from this method:
> {code}
> org.apache.cxf.jaxrs.utils.InjectionUtils.fillInValuesFromBean(Object,
> String, MultivaluedMap<String, Object>)
> {code}
> specifically, this piece of code, which assumes the value is not null, and
> thus causes a NullPointerException if it is null:
> {code}
> Object value = extractFromMethod(bean, m);
> if (isPrimitive(value.getClass())) {
> values.putSingle(propertyName, value);
> } else if (isSupportedCollectionOrArray(value.getClass())) {
> // ignoring arrrays for a moment
> List<Object> theValues = null;
> if (value.getClass().isArray()) {
> theValues = Arrays.asList(value);
> } else {
> theValues = CastUtils.cast((List<?>)value);
> }
> values.put(propertyName, theValues);
> } else {
> fillInValuesFromBean(value, propertyName, values);
> }
> {code}
> Ideally, if a value is null, one should just ignore the property and not add
> it to the parameter map.
