[Qgis-user] Project not loading in web client

Tue Feb 18 16:31:37 PST 2014

CC'ing back to the list, in case this can help someone down the track 
through the list archive.

Thanks for the help Bernhard. I got there in the end.

The CRS mismatch (as described below) wasn't actually causing the 
problem, although it did cause other issues if I got the map to load.

The problem with the map not loading was being caused by not having the 
"Service Capabilities" box checked in Project Properties/OWS Server. 
Once that's turned on, the project loads fine in the web client (albeit 
with other issues unless the CRS stuff is sorted out also). Rookie 
mistake, obviously.

Thanks again.

Hi Bernhard,

Aah, ok. I didn't realise the client and the project had to match,
figuring it would re-project if it had to.

I've tried your suggestions, changing everything to EPSG:4283 which is
the CRS I will need to use. There was no EPSG4283.js in
/site/libs/proj4js so created one using the flags for that CRS shown in
the QGIS desktop (should this work?). I still had the same behaviour.

At this point I thought it might be something to do with EPSG4283, so I
tried changing everything to EPSG3857 (including converting the source
data) as I know that works for the example projects. It still doesn't
work though. Failure mode is the same as before.

This is the version with everything in EPSG3857 if you want to have a look:

http://xxxxxx/qgiswebclient.html?map=/usr/local/share/qgis-web-client/projects/testshape3857.qgs

Thanks for your help with this!
