Trunk : Null pointer exception in SCA Data binding for SDO
Hi,
Is anything seeing on the trunk ? I updated and am trying a clean build.
testTransform(org.apache.tuscany.sca.databinding.sdo.DataObject2NodeTestCase)
Time elapsed: 0.02 sec <<< ERROR!
org.apache.tuscany.sca.databinding.TransformationException:
java.lang.NullPointerException
at org.apache.tuscany.sca.databinding.sdo.Node2DataObject.transform(
Node2DataObject.java:47)
at
org.apache.tuscany.sca.databinding.sdo.DataObject2NodeTestCase.testTransform
(DataObject2NodeTestCase.java
53)
Thanks
- Venkat

It seems to go off into the sdo xmlhelper which inturn further goes into
emf-ecore-xmi-2.2.3 classes. I couldn't get the concise source for this and
ended up downloading
http://www.eclipse.org/downloads/download.php?file=/modeling/emf/emf/downloads/drops/2.2.3/R200705141058/emf-sdo-xsd-SDK-2.2.3.zipand
extracting the source.

I don't see this problem.
Which EMF version are you seeing? The 'billTo' is an unqualified element
under the 'purchaseOrder' element and the namespace URI is null.
Thanks,
Raymond

Hi,
Further looking, it seems like the namespaceUri for 'billTo' child element
is null and down there in the emf there is some code that does
namespaceUri.length() and thats the source for the NPE. Am I alone in this
problem ? Where could I be going wrong ?

Hi Raymond, thanks for responding. This seems like something weird as it

Hi, Venkat.
Can you provide the full stacktrace? If you can debug out which variable is
null, it would be even better.
