[Qgis-user] R: qgisserver for publishing external WFS

[Eugenio Trumpy]

Hi Richard,

I'm following the bug evolution in github.
However, I tried this solution/workaround:

https://github.com/qgis/QGIS/issues/25847

It worked to me.

Eugenio

Mmm, I did myself. And if you ask me you hit a bug... :-(

It appears that 'cascading' just works for at least WMS.

BUT... cascading my test WFS fails because it looks like it 'rewrites' the returned GML, resulting in invalid xml/gml

IF the original features had a 'namespace' (in my case: test:provincies), apparently QGIS adds  it's own namespace  (qgs:) to it, resulting in
invalid xml (not more then one ':' is allowed), AND making the gml at unreadable for OGR/GDAL (while it reports the right layers, it cannot read the featureMembers: (see the "qgs:test:provincies" parts):

<gml:featureMember>

I created an issue for it:
