[Geotools-devel] [jira] (GEOT-4417) App-schema joining with toXlinkHref gives empty results

Wed, 13 Mar 2013 02:47:27 -0700

Issue Type: Bug Bug
Affects Versions: 9.0-RC1
Assignee: Rini Angreani
Components: app-schema plugin
Created: 13/Mar/13 4:44 AM
Description:

With joining and feature chaining, toXlinkHref gives empty results when filtered. 

<sourceExpression>
    <OCQL>SITE_ID</OCQL>
    <linkElement> if_then_else(isNull(HASRELATEDACTIVITY),toXlinkHref('urn:ogc:def:nil:OGC:1.0:missing'),'er:MiningActivity')
    </linkElement>
    <linkField>FEATURE_LINK[2]</linkField>
</sourceExpression>



This is because joining relies on the order of chained data and toXlinkHref skips the feature chained data without updating the skipped index.

Then when the if_then_else condition is meant to return feature chained data, it starts from the wrong index where the foreign keys don't match.
Fix Versions: 9.0-RC2
