    # TODO make GetFeatureInfo show what's in the display expression and enable test
    def testGetFeatureInfoRelationReference(self):
        """Test GetFeatureInfo solves "relation reference" widget "display expression" values""" 
        mypath = self.testdata_path + "test_project_values.qgz" 
                                 '&layers=layer2&styles=&' +
                                 'VERSION=1.3.0&' +
                                 'info_format=text%2Fxml&' +
                                 'width=926&height=787&srs=EPSG%3A4326' +
                                 '&bbox=912217,5605059,914099,5606652' +
                                 '&CRS=EPSG:3857' +
                                 '&FEATURE_COUNT=10' +
                                 '&WITH_GEOMETRY=True' +

The server should have resolved the values and output:

 <Layer name="layer2">
  <Feature id="1">
   <Attribute value="value PE 1000 PN6" name="id"/>

but it outputs instead:

 <Layer name="layer2">
  <Feature id="1">
   <Attribute value="1" name="id"/>

Can you please check current master?

#2 Updated by Tudor Bărăscu over 1 year ago

Hi Alessandro, yes.. I can replicate..

It seems somehow the qgz is corrupted or something.. again.. (see https://github.com/qgis/QGIS/pull/7867 )

Until I try to fix it fully and maybe get to the bottom of this I've attached the test_project_values.qgs project that you can use and debug. You have the request in the tests and just need to change ggz to qgs for that specific test. Of course, the project needs to be in the tests/testdata/qgis_server/ dir.

Thanks a lot for you very precious work.

You can replicate now even with the qgz project (getCapabilities not working on it though) so please let me know if there's anything else that I can do. Thank you.
