Hi Florent,
This should really go to geoserver-users mailing list.
Try this:
<AttributeMapping>
<targetAttribute>au:admUnit</targetAttribute>
<ClientProperty>
<name>xlink:href</name>
<value>strConcat('urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:',
if_then_else(isNull(inspireid),'missing', strTrim(inspireid)))</value>
</ClientProperty>
<ClientProperty>
<name>nilReason</name>
<value> if_then_else(isNull(inspireid), 'unknown',
Expression.NIL)</value>
</ClientProperty>
</AttributeMapping>
You should either get:
<au:admUnit
xlink:href="urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:FR2100000000">
or
<au:admUnit
href="urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:missing"
nilReason="unknown"/>
Cheers

Hi,
Yes thank you, the sourceExpression was messing things out you are right cause
if no link is found, it won't encode the element.
Your way is better and i can get the behavior i want. The only difference i
found is that, if the "inspireid" is not null, but doesn't refer to any linked
feature, it will be encoded while whith the linkElement, if no link was found
it could know it and don't encode the element.
But whatever, source data should be populated correctly and have a foreign key
to avoid mistake anyway.
Last thing maybe you could help is about encoding attribute with ClientProperty
<ClientProperty>
<name>nilReason</name>
<value>if_then_else(isNull(inspireid), 'unknown', '')</value>
</ClientProperty>
i would like that if inspireid is not null, that the attribute nilReason won't
be encoded..
The way i found below still encode attribute with nilReason=""
Thanks for your help
Cheers

The one you had didn't work because it has <sourceExpression> with linkElement.
This means the element will only be encoded if there's a match in the linked
feature.
The element would have some content from the linked/chained feature, and
xlink:href from the ClientProperty.
It would look like something like this:
<au:admUnit
xlink:href="urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:FR2100000000">
<au:AdministrativeUnit>
.....
</au:AdministrativeUnit>
</au:admUnit>
If you only need to encode xlink:href, then you don't need to specify
sourceExpression.
Normally xlink:href is only used if there is no content in the element anyway.
Cheers

Hi Rini,
thks for reply, it was actually right that my mapping file contained errors.
now it's better, even thouh i can't figure out some behavior ...
for example, if i have a xlink:href element :
<au:admUnit
href="urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:FR2100000000"/>
the element is added if the link is found, but hidden if no link is found
what i would like, if no link is found, is that the element is still there with
:
<au:admUnit
href="urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:missing"/>
my definition :
<AttributeMapping>
<targetAttribute>au:admUnit</targetAttribute>
<sourceExpression>
<OCQL>strTrim(admunit)</OCQL>
<linkElement>au:AdministrativeUnit</linkElement>
<linkField>FEATURE_LINK</linkField>
</sourceExpression>
<isMultiple>true</isMultiple>
<encodeIfEmpty>true</encodeIfEmpty>
<ClientProperty>
<name>xlink:href</name>
<value>strConcat('urn:x-inspire:specification:gmlas:AdministrativeUnits:3.0:',
if_then_else(isNull(inspireid),'missing', strTrim(inspireid)))</value>
</ClientProperty>
</AttributeMapping>

Hi Florent,
Sorry for the late reply. I missed this one.
You are missing an <Include> tag inside <includedTypes>.
It should look like this:
<includedTypes>
<Include>spellingOfName.xml</Include>
</includedTypes>
To make things easier, you can copy AppSchemaDataAccess.xsd into the same
directory with your mapping file and validate your mapping file against it.
The latest schema can be found here:
https://github.com/geotools/geotools/blob/master/modules/extension/app-schema/app-schema/src/test/resources/test-data/AppSchemaDataAccess.xsd
Cheers
Rini
