Wrong namespace (nts) on request parameter in filter for wfs 2.0

[dahermansson]

When we use the service at https://cite.opengeospatial.org/teamengine/rest/suites/wfs20/ with the Inspire Validator we get faild tests on a bunch of tests which looks like the reason to fail is a request with a filter thats not correct. The namespace on the field in the filter is set to "tns" like in tns:Identifier
the correct way to create the filter is to use gml:Identifier
As described in the Issue 746 at Inspire-Validator we can't find any reason for it to use "tnf" as prefix/namespace in the requests.

To Reproduce
Steps to reproduce the behavior:
Validate a Inspire WFS-service.

Expected behavior
Corrected formated filters using the expected field.

Thank you for reporting.
As this behavior is related to the WFS 2.0 test suite, I moved the issue to the ets-wfs20 issue tracker.

I can confirm that several tests fail on Production (http://cite.ogc.org/teamengine/) and Beta (http://cite.ogc.org/te2/).

Following test fails several times:

This was already described in the description of this issue.

However, several other tests also fail but with a different error message: E.g. property Is Greater Than_match Any, get Features By Type or property Is Less Than Equal To_match Any.
@dahermansson Are you aware of those additional failures?

@bpross-52n Can you please do a deeper analysis why the property Is Not Like tests fail as documented above?

@dahermansson
It appears that your service is ignoring the declaration of namespaces.
Please see following snippet of the request:

<ValueReference xmlns:tns="http://www.opengis.net/gml/3.2">tns:identifier</ValueReference>

The GML namespace is bound to tns prefix. So, the correct namespace is used in the request.

You need to configure your server to be namespace aware.
