QgsMapCanvas.refresh() doesn't reload WMS layer

Reported by: trapanator Owned by: nobody
Priority: major: does not work as expected Milestone: Version 1.7.0
Component: MapCanvas Version: Trunk

Must Fix for Release: Yes Platform: Windows
Platform Version: Awaiting user input: no

Description

In a plugin I add a feature to a PostGIS layer. I have another WMS raster layer connected to this PostGIS layer.

If I invoke the command: 

      QgsMapCanvas.refresh()

it refreshes the map but not the WMS layer. A workaround is this (note: 'e' variable is QMouseEvent type): 

     self.myCanvas.panAction(e)
     self.myCanvas.panActionEnd(QPoint (e.x(), e.y()))

Try to reload the layers before refreshing the canvas (that's how qgisapp does it):

C++: QgsMapLayerRegistry::instance()->reloadAllLayers(); mMapCanvas->refresh();

Python: QgsMapLayerRegistry.instance().reloadAllLayers() qgis.utils.iface.mapCanvas().refresh()

Hope it works (otherwise reopen the ticket)
