NullPointerException when reading a soap encoded struct with a nested element
that's nil
----------------------------------------------------------------------------------------
Key: CXF-2695
URL: https://issues.apache.org/jira/browse/CXF-2695
Project: CXF
Issue Type: Bug
Components: Aegis Databinding
Affects Versions: 2.2.6
Reporter: Marinó A. Jónsson
When reading a simple struct that has a nested (unqualified) element set to nil
a NullPointerException is thrown:
{code}
java.lang.NullPointerException
at
org.apache.cxf.aegis.type.basic.BeanTypeInfo.isNillable(BeanTypeInfo.java:384)
at
org.apache.cxf.aegis.type.basic.BeanType.readObject(BeanType.java:165)
{code}
This should be easily replicated by using the following xml for the
StructTypeTest.testSimpleStruct() test:
{code}
<b:shipping xmlns:b="urn:Bean"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<street>1234 Riverside Drive</street>
<city>Gainesville</city>
<state>FL</state>
<zip xsi:nil="true"/>
</b:shipping>
{code}
Apparently the problem stems from the fact that when the element is nil it's
handled without involving the StructType (which takes care of "qualifying" the
element name in other cases) - the unqualified name of the element is sent to
the BeanTypeInfo.isNillable() method, which fails to find a Type for the name
as a result.
I'm not sure how to solve this in a "clean" way - maybe extracting the "else"
block that handles nil elements in BeanType.readObject to a seperate
overridable method thereby giving StructType a chance to qualify the name
before it's sent to the BeanTypeInfo.isNillable() method?
