Sorry folks, accidentally hit send on that too early. Here's the message I
wanted to send:
Hello all,
I'm trying to make an SLD where a user can change the label field at runtime,
but I'm running into problems getting the "property" function to work as
expected with my data source. The source is producing complex features, and
they show up in geoserver as namespaced. If I prefix a property with the
namespace in <PropertyName>, everything works as expected, but when I try to
use <Function name="property">, I hit errors.
A snippet like this works fine:
<Label>
<ogc:PropertyName>namespace:myFeature</ogc:PropertyName>
</Label>
This fails with "The style specified an attribute named 'namespace:myFeature',
not found in the 'namespace:layer' layer" (and similarly fails if I pass in a
valid namespace-prefixed property name in the request):
<Label>
<ogc:Function name="property">
<ogc:Function name="env">
<ogc:Literal>userDefinedLabel</ogc:Literal>
<ogc:Literal>namespace:myFeature</ogc:Literal>
</ogc:Function>
</ogc:Function>
</Label>
I've tried a few different variations on the above (for example, removing
prefixes or adding the full URL of the prefix) without success. The latter
recipe also worked fine on a simple feature with no namespace, it's just the
complex feature with the namespace that caused things to break. I've been
digging through Google all day but have not found anything applicable to this
scenario. I'd appreciate any suggestions that you all have on what I might be
doing wrong here.
I am using GeoServer 2.17.3 with OpenJDK 1.8.0_272 Server running in a Linux
container. I know, they're old - unfortunately upgrades to newer versions are
not a priority right now.
Best,
Chris Reffett

Hello all,
I'm trying to write an SLD but am having trouble getting the "property"
function to work as expected. In short, I have a layer that has namespaced
fields (it's coming from a data source that produces complex features) and am
trying to make the label on those features able to be set by an env variable in
a request.
This wor
I am using geoserver 2.17.3 - sorry, I know it's out of date, it'll be some
time before we can update.
