Description

Hello guys and gals.

First of all, here's my setup:

  • Ubuntu 13.01
  • QGis installed from ubuntugis-unstable ppa;
  • QGis 2.0;
  • PostGIS 2.0;
  • PostgreSQL 9.1;

I have a database with a SIRGAS UTM projection and a project with web mercator projection. I can edit my data as usual, and it's just fine. The map is on web mercator because of OpenLayers plugin layer added to the map.

I've tried to use the topology checker with Web Mercator projection, and it reports no errors. If I remove the OpenLayers plugin layer and configure the map to my original SRID, the topology checker works just fine and reports errors as usual.

I have not tried to test two layer topology when the layers are in different projections, but it seems that whenever the map is configured to a projection different than the layer's in test projection, the topology checker does not work.

Here the plugin works - the only issue is that the zoom to invalid record is aways done on the original projection, so if OTF is enabled, it zooms to a wrong area.
