[Geoserver-users] Number of decimal places in WFS

[Antonis Christofides]

Hello,

I have a layer which has some properties that geoserver indicates are "Double".
If I get these properties through WFS (e.g.
http://chemicalse.etme.gr/geoserver/etme/ows?service=WFS&version=1.1.0&request=GetFeature&typename=etme:DIKTYO_EPIFANEIAKWN_POTAMIA&srsname=EPSG:3857&outputformat=gml3),
here is (part of) what I get (I've bolded the problem):

<etme:DIKTYO_EPIFANEIAKWN_POTAMIA gml:id="DIKTYO_EPIFANEIAKWN_POTAMIA.1">
<etme:the_geom>
<gml:Point srsName="http://www.opengis.net/gml/srs/epsg.xml#3857" srsDimension="2">
<gml:pos>2413731.81975826 4690224.47314216</gml:pos>
</gml:Point>
</etme:the_geom>
***<etme:A_A>1.0</etme:A_A>*
<etme:CODE>1-P-KARPENISIOTIS</etme:CODE>
<etme:P_E>Åõñõôáíßáò</etme:P_E>
</etme:DIKTYO_EPIFANEIAKWN_POTAMIA>

OpenLayers thinks that the etme:A_A property is a string (whereas in geoserver,
as I said, it is registered as "Double"). Is this a geoserver issue or a WFS
limitation?

In addition, if I ask for json instead of gml3, the value is still a string, but
it shows as "1", without decimal places. Why is this?

(I'm running geoserver 2.11.1).

Thanks!

It's an issue in OpenLayers, I guess it's not running DescribeFeatureType
to determine the attribute type? The schema says double:

http://chemicalse.etme.gr/geoserver/etme/ows?service=WFS&version=1.1.0&request=DescribeFeatureType&typename=etme:DIKTYO_EPIFANEIAKWN_POTAMIA

I don't see that, run as json and got a number:

http://chemicalse.etme.gr/geoserver/etme/ows?service=WFS&version=1.1.0&request=GetFeature&typename=etme:DIKTYO_EPIFANEIAKWN_POTAMIA&srsname=EPSG:3857&outputformat=application/json

...
type: "Feature",
id: "DIKTYO_EPIFANEIAKWN_POTAMIA.1",
geometry: {
type: "Point",
coordinates: [
2413731.81975826,
4690224.47314216
]
},
geometry_name: "the_geom",
properties: {
*A_A: 1,*
CODE: "1-P-KARPENISIOTIS",
X: 298578,
Y: 4294639,
P_E: "ΕυρυταΜίας"
