Hi David,
We have come across a problem in the WFS code (specifically 2.1.x) where
the feature type schema is only loaded properly if a call to
WFSDataStore.getFeatureReader() is made before performing any
transactions (addFeatures()).
Specifically it looks like the getFeatureReader() call loads the feature
type schema into the SchemaFactory, and it must be loaded in order to
commit features.
Here is the exception:
java.lang.NullPointerException
at
org.geotools.xml.wfs.WFSTransactionComplexTypes$InsertElementType.encode(WFSTransactionComplexTypes.java:915)
at
org.geotools.xml.wfs.WFSTransactionComplexTypes$TransactionType.encode(WFSTransactionComplexTypes.java:300)
at
org.geotools.xml.DocumentWriter.writeFragment(DocumentWriter.java:309)

org.geotools.xml.DocumentWriter.writeDocument(DocumentWriter.java:208)

org.geotools.data.wfs.WFSTransactionState.commitPost(WFSTransactionState.java:190)
at
org.geotools.data.wfs.WFSTransactionState.commit(WFSTransactionState.java:110)
at
org.geotools.data.wfs.WFSFeatureStore.addFeatures(WFSFeatureStore.java:109)
...
If I add the following call before addFeatures() is called, everything
works fine.
FeatureReader reader = dataStore.getFeatureReader(query,
Transaction.AUTO_COMMIT);
I wrote a test case, but it is not very useful as it uses and hits local
data and a geoserver on my machine, but I can probably make it public if
you would like.
