by pkovgan
Hi!
I've got this error durin BP execution, what does it mean?
I know that failure occures during second assign, but do not know where exactly, what you can propose to debug?
This failure is very quiet , except this message I have nothing to track problem.
Thanks!

[JBoss jBPM] - Re: invoke called, but our invoker is disconnected
by alex.guizar＠jboss.com
The NPE is thrown because operPartAccessor is null.
// get part accessor from operation wrapper
| SOAPElement operPartAccessor = XmlUtil.getElement(operationElem, partName);
>From the javadoc for XmlUtil.getElement(SOAPElement parent, String localName):
anonymous wrote : Gets the first child element of the given SOAP element with the specified local name and a null or empty namespace URI.
| @return the corresponding child element, or null if there is no match
In our case, operationElem has a child element that matches the part name. However, the namespace URI is not empty; it is equal to the namespace specified in the soap:body element in the WSDL binding output:
<binding name="SchufaServiceSoapBinding" type="tns:SchufaWS">
| <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/>
| <operation name="validCustomer">
| <soap:operation soapAction="urn:samples:schufa:validCustomer"/>
| <input>
| <soap:body use="literal" namespace="urn:samples:schufa"/>
| </input>
| <output>
| <soap:body use="literal" namespace="urn:samples:schufa"/>
| </output>
| </operation>
| </binding>
Try retrieving the part accessor from the operation element with the following code:
// get part accessor from operation wrapper
| SOAPElement operPartAccessor = XmlUtil.getElement(
| operationElem,
| soapBody.getNamespaceURI(),
| partName);
