Using the 8-25-10 build, I do not get this NullPointer exception. However,
WFS response documents are returning MappedFeatures where the
gsmlcore:metadata element is empty, when it should not be... I've gotten the
service live, so feel free to take a look at http://debug.usgin.org/gsml.
This is running the most recent nightly build.
Empty elements makes me think there's some kind of backend data problem, but
I've double-checked and can't find it. To explain, the isp:MD_Metadata
mapping looks like:
<AttributeMapping>
<targetAttribute>FEATURE_LINK[1]</targetAttribute>
<sourceExpression>
<OCQL>datasources_id</OCQL>
</sourceExpression>
</AttributeMapping>
The chaining from the MappedFeature looks like:
<AttributeMapping>
<targetAttribute>gsmlcore:metadata</targetAttribute>
<sourceExpression>
<OCQL>datasourceid</OCQL>
<linkElement>isp:MD_Metadata</linkElement>
<linkField>FEATURE_LINK[1]</linkField>
</sourceExpression>
<isMultiple>false</isMultiple>
</AttributeMapping>
And this returns empty gsmlcore:metadata elements. However, the SQL Query:
SELECT mapunitpolys.mapunit, datasources.source
FROM ncgmp.mapunitpolys LEFT JOIN ncgmp.datasources ON
mapunitpolys.datasourceid = datasources.datasources_id
WHERE datasources.source IS NULL;
... does not return any records, indicating that every MappedFeature (from
the mapunitpolys table) has an associated MD_Metadata feature (from the
datasources table), but for some reason it is not coming through in the WFS
response.
Thanks,
Ryan

Attached are the mappings I'm using. I double-checked, and there are no null
values in the backend tables relating to this particular attribute mapping.
I'm using a dump from svn trunk that I took about a month ago - not exactly
sure what day it was. Today I'll be trying to set things up in a live
environment with the lastest nightly build.
Thanks for taking a look!

Hi Ryan,
Which build version are you using?
Would you be able to send the mapping files? I ran into a similar issue in
the past and it was due to null values in the database even though the
schema is set to minOccur=0
I have submitted a patch for this last month
http://jira.codehaus.org/browse/GEOT-2679
Perhaps you can try with the latest version from trunk which is build from
our buildbot :)
