Description

Working on our plugin, I encountered this strange behavior: a WMS layer is displayed in the layers list with its legend but there is nothing in the map canvas.

To reproduce:

  1. open WMS client and add this WMS url: http://ws.carmencarto.fr/WMS/105/ONF_Forets
  2. when you press the "Connect" button, the list is displayed
  3. selecting the layer "Parcelles_Forestieres" the "Add" button is disabled and status bar displays "No CRS selected"
  4. select another layer and select back the layer, now "Add" button is enabled and CRS Lambert RGF93 (EPSG:2154) is set
  5. clicking "Add" produces an empty mapcanvas but a legend present because the minimum scale visibility is not read from the server

=> there are messages in the log window, WMS tab (see screenshot)

Notice that:
  • the others layers from the same WMS service are okay (I unchecked on the screenshot but you can try)
