Generated ADBBean: Issue with getPullParser() method for optional attributes
----------------------------------------------------------------------------

                 Key: AXIS2-3028
                 URL: https://issues.apache.org/jira/browse/AXIS2-3028
             Project: Axis 2.0 (Axis2)
          Issue Type: Bug
          Components: codegen
    Affects Versions: 1.2
            Reporter: Tobias Jordan


A complexType in my XSD file contains a optional attribute. For example:

<xs:complexType name="foo_T">
     <xs:attribute use="optional" name="bla" type="bla_T">
</xs:complexType>

The generated ADBBean class Foo_T.java has the following code part in the getPullParser()
method:

attribList.add(new javax.xml.namespace.QName("", "bla"));
attribList.add(localBla.toString());

And here comes the issue:

I wrote a custom handler to print the SOAP messages to stdout:

SOAPEnvelope env = msgContext.getEnvelope();
System.out.println(env.toString());

For messages containing an optional attribute as described above, the toString() call on the
SOAP envelope results in a NullPointerException. The NullPointer occurs because toString()
ends up in the getPullParser() method and the localBla variable isn't set (since it is optional!).

So I guess there is a missing check against null in the generated code.
