Hello all,
I'm hoping someone can help me resolve an issue I've been experiencing while
using the app-schema plugin within GeoServer 2.10.0 using GeoTools 16. I'm
trying to map some DB data into a WXXM schema
(http://www.wxxm.aero/schema/2.0/wxxm.xsd), but one of the elements refuses to
encode. I believe this is due to the manner in which the elements are defined,
but the definitions are valid so I'm hoping there's something I can do to get
the mapping to work.
The elements in question are wxxm:DiscreteCoverage and wxxm:domainSet.
wxxm:DiscreteCoverage extends gml:DiscreteCoverage, but does not add any
attributes. gml:DiscreteCoverage contains a gml:domainSet among other
elements. wxxm:domainSet is defined as a substitution for gml:domainSet.
The issue I see via the debugger is that when GMLEncodingUtils.java calls
Schemas.getChildElementParticles(type, true); on line 157 passing in the
wxxm:DiscreteCoverage type, the returned list of particles only contains
gml:domainSet (which *does* list wxxm:domainSet as a substitionGroup within
it). Later on line 222 it uses the propertyName from the particles to attempt
to retrieve properties from the feature to encode, but it does not attempt to
use any substitutionGroup definitions for retrieval.
Depending on my mapping file I experience two different results from the call
on line 222:
1) If I defined the targetAttribute as wxxm:domainSet, then the call returns
nothing and no domainSet element is encoded.
2) If I defined the targetAttribute as gml:domainSet (with targetAttributeNode
of wxxm:DomainSetType), then the call returns the domainSet object, but it
encodes it as a gml:domainSet which prevents any wxxm:domainSet elements from
encoding.
Am I missing something in how this mapping is defined? My expected output is
as follows.
<wxxm:DiscreteCoverage gml:id="id0">
<gml:name>Discrete_Coverage_Name</gml:name>
<wxxm:domainSet>
<wxxm:DomainObject gml:id="id1">
<wxxm:elements>
.
</wxxm:elements>
</wxxm:DomainObject>
</wxxm:domainSet>
</wxxm:DiscreteCoverage>
Any help would be greatly appreciated.
