Hi Justin,
Since you're the author of the class, I'm wondering if you could help me.
In SimpleFeaturePropertyAccessor.canHandle(), it does this:
if ( object instanceof SimpleFeature ) {
return ((SimpleFeature) object).getAttribute( xpath ) != null;
}
When we have a null value in the database, it then starts using the next
accessor for the next rows, which is XPathPropertyAccessor.
XPathPropertyAccessor doesn't only return the value of the column, but wrapping
it with an xpath place holder.
i.e. this is what's encoded:
<gsml:mineralName
xlink:href="http://resource.nvcl.au/classifier/auscope/tsa/6.1/mineral/SimpleFeatureImpl.Attribute:
CLASSTEXT<CLASSTEXT id=LOGDATA10M.fid--5710a6a2_125b91b4e25_-7fe8>=Sulfate" />
whereas, this is what we want:
<gsml:mineralName
xlink:href="http://resource.nvcl.au/classifier/auscope/tsa/6.1/mineral/Sulfate";
/>
Our workaround so far is to replace null values with null string
representations in the database, e.g. 'N/A'.
Is this a bug?
Is it meant to check if the attribute exists in the feature, i.e.
return ((SimpleFeature) object).getProperty( xpath ) != null;
instead?
Thank you and regards,
Rini
