[Qgis-user] Unable to open attribute table wfs PyQGIS via proxy

[Arjun Dongre]

Hello,
I am building out a workflow for our team to access their data with a wfs
connection in a plugin. I am creating a wfs layer through QgsVectorLayer
and can successfully add it to the map. However when I try to open the
attribute table the entire program freezes.

One caveat is that I am using a proxy to send requests to geoserver over an
https connection. One thing I have found I need to do is do a global
replace in the getcapabilities document to point the urls to the proxy
domain and not directly back to geoserver.  I have successfully implemented
this pattern for WMS data.

Another oddity is that if I enable feature count in the TOC, I can then
open the table successfully, however if I change/set a filter and try to
reopen the table the program will freeze as before. So it seems that my
methodology does work.

When I create the layer by hitting geoserver directly I do not have this
issue.

I have installed the nightly build to try and look at any error messages,
but it freezes before anything is written out. I also do not see any issues
in the logs for geoserver or in the IIS based proxy.

Any help or ideas would be greatly appreciated.

Thank you.
